Episode Overview

In this episode of My Weird Prompts, Herman and Corn Poppleberry tackle a modern tech frustration: why is it still so difficult to access your own financial data in 2025? Inspired by their housemate Daniel’s struggle to automate his finances with n8n, the duo explores the shifting regulatory landscape and the implementation of the CFPB’s Section 1033 rule. They break down the heated debate between secure APIs and risky screen scraping, and why giants like Google and PayPal are hesitant to let go of their lucrative data "moats." From the technical standards of the FDX to the democratization of banking, this episode is a deep dive into who really owns your transaction history and what’s being done to give that power back to the consumer.

In the latest episode of My Weird Prompts, brothers Herman and Corn Poppleberry sit down in their Jerusalem home to tackle a question that has plagued tech enthusiasts and casual savers alike: in an era of instant communication and AI-driven automation, why is accessing our own financial data still stuck in the nineties?

The discussion was sparked by their housemate Daniel, an automation enthusiast who found himself hitting a brick wall while trying to integrate his financial life into n8n, a workflow automation tool. Daniel’s frustration stems from a common hurdle—the inability to access real-time API (Application Programming Interface) data from major financial institutions, forcing him to rely on the archaic process of downloading and manually merging CSV files.

The Regulatory Landscape: Section 1033

Herman Poppleberry opens the discussion by highlighting that this isn't just a technical grievance; it is a legal and regulatory battleground. He points to the Consumer Financial Protection Bureau (CFPB) and the finalized Section 1033 rule. This rule, a cornerstone of the "open banking" movement in the United States, mandates that financial institutions must make consumer data available to the consumers themselves and authorized third parties without prohibitive fees or unnecessary complexity.

While the rule was finalized in late 2024, Herman explains that the industry is currently in the "thick of the implementation phase" as of late 2025. The goal is to jumpstart a financial ecosystem where the consumer, not the bank, owns the data.

Security vs. Accessibility

The conversation takes a turn when Corn, the more cautious of the two, expresses his "sloth-like" hesitation toward high-speed data integrations. Corn raises a valid concern: does opening an API to a bank account essentially put a "rob me" sign out for hackers?

Herman counters this by explaining the dangers of the current status quo: screen scraping. Currently, many budgeting apps require users to hand over their actual usernames and passwords. A bot then logs in as the user and "scrapes" the data off the screen. Herman argues that a permissioned API is significantly more secure. It uses tokens that allow "read-only" access, meaning a tool can see transactions but cannot move money, and access can be revoked instantly without changing a password.

The "Moat" and the Tech Giants

A significant portion of the episode focuses on why companies like Google and PayPal seem to be lagging behind. Corn notes that for these giants, transaction data is a massive competitive advantage. If Google knows exactly what you buy and where, they have a "moat" that protects their advertising and product ecosystems.

Herman points out that while traditional banks were the initial focus of Section 1033, the CFPB has expanded its scope to include "digital wallets" and payment processors. For many younger consumers, companies like Apple and PayPal act as their primary financial interface, making their compliance vital for true financial democratization. Herman argues that the lack of a consumer-facing API from these companies is a "choice, not a technical limitation."

The Role of Standards and Middlemen

The brothers also delve into the technical side of the transition, mentioning the Financial Data Exchange (FDX). This non-profit consortium is working to create a unified standard for data sharing so that every small credit union doesn't have to reinvent the wheel.

However, they also discuss the "Plaid problem." While companies like Plaid have moved away from scraping and toward data access agreements, Corn expresses concern that this simply replaces one gatekeeper with another. If an individual like Daniel wants to write his own code to talk to his bank, he shouldn't be forced to go through a massive corporate middleman that also collects his data in the process.

Small Banks and the Cost of Compliance

Corn, ever the advocate for the "little guy," raises the issue of small credit unions. He questions whether the burden of building expensive API infrastructures will eventually crush smaller institutions, further consolidating power in the hands of Big Tech. Herman notes that the CFPB has accounted for this by giving smaller institutions a longer timeline to comply, but the tension between innovation and the cost of entry remains a central theme of the open banking debate.

Conclusion: The Path to 2025 and Beyond

The episode concludes with a look toward the future. Herman and Corn agree that while the transition is messy, the shift toward open banking is inevitable. The "privacy fog" (humorously referenced in a mid-episode advertisement for the Larry-Co Instant Privacy Fogger) is slowly lifting from our financial records.

For users like Daniel, the dream is simple: a world where your money works for you, and your data is accessible, portable, and secure. As the Section 1033 rules continue to roll out through the end of 2025, the "nineteen ninety-nine" era of manual spreadsheets may finally be coming to a close.

Episode #222: The Fight for Your Financial Data: Why APIs Matter

Corn
Welcome to My Weird Prompts. I am Corn, and I am joined as always by my brother, Herman Poppleberry. We are coming to you from our home here in Jerusalem, and today we have a really interesting topic that our housemate Daniel sent over to us. He has been diving deep into automation lately, specifically using a tool called n eight n to manage his life, but he ran into a major roadblock when it comes to his own money.
Herman
It is a classic problem, Corn. Daniel is basically asking why, in the year two thousand twenty-five, it is still so incredibly difficult to actually own and access your own financial data. He is tired of downloading comma separated value files and wants real, live application programming interface access to his transactions. And honestly, it is about time we talk about this because the regulatory landscape has been shifting under our feet for the last year.
Corn
I have to be honest, Herman, when Daniel first showed me his automation workflows, I was a little bit intimidated. Being a sloth, I tend to move a bit slower than these high speed data integrations. But even I can see how annoying it is. If I want to see how much I spent on eucalyptus leaves last month, I have to log into three different apps, download files, and then try to mash them together in a spreadsheet. It feels very nineteen ninety-nine.
Herman
It is exactly nineteen ninety-nine, and that is by design. These institutions, the banks, the payment giants like PayPal and Google, they treat your transaction history like their private property. But here is the kicker, Corn. There has been a huge push to change this. Specifically, the Consumer Financial Protection Bureau, or the C F P B, has been working on something called the Section ten thirty-three rule. They actually finalized a big part of it back in October of two thousand twenty-four, and we are right in the thick of the implementation phase here in late twenty-five.
Corn
Wait, hold on. You are saying there is actually a law or a rule that says they have to give us our data? Because it definitely does not feel like that when I am trying to navigate the PayPal developer portal.
Herman
Well, that is where it gets messy. The rule is meant to jumpstart what we call open banking in the United States. It basically says that financial institutions have to make your data available to you, and to third parties you authorize, without charging you a fee and without making it a total nightmare. But as Daniel noticed, companies like PayPal and Google have a very different relationship with their data than a traditional bank might.
Corn
I mean, I can see why they would be hesitant. If I am Google or PayPal, my whole business is knowing what people buy. If I just give that away to any automation tool Daniel plugs in, am I not losing my competitive edge? Or worse, am I not putting Daniel at risk? I worry about the security side of this, Herman. If I open an A P I to my bank account, isn't that just a giant "rob me" sign for hackers?
Herman
See, I actually see it differently. Right now, most people who use these financial apps are doing something called screen scraping. That is where you give a third party app your actual username and password, and then a bot logs in as you and literally reads the screen. That is way more dangerous than a secure, permissioned A P I. An A P I allows you to say, "Hey, this specific tool can only read my transaction history, it cannot move money, and I can revoke its access in one click." It is actually much more secure than the current mess we have.
Corn
Hmm, I suppose that makes sense. But it still feels like a lot of power to hand over to a script. Daniel mentioned he is using n eight n, which is great because he hosts it himself, but most people are using cloud services. I don't know, Herman, I feel like the banks might be doing us a favor by making it a little bit difficult. It forces you to be intentional, right?
Herman
Nah, I don't think so, Corn. That sounds like an excuse for bad technology. Think about it. If you want to build a budget, you should be able to see your data in real time. You shouldn't have to wait for a monthly statement or a C S V export. The people leading the push for this are groups like the Financial Data Exchange, or F D X. They are a non-profit consortium of banks, fintechs, and consumer groups trying to set a single standard for how this data is shared.
Corn
F D X? That sounds like a shipping company.
Herman
Totally different thing. They are the ones creating the technical blueprints so that every bank doesn't have a different, broken way of sharing data. And then you have the advocacy side. Groups like the American Bankers Association are involved, though they have been a bit more cautious, often pushing back on how fast these rules are implemented. They are worried about the costs for smaller banks.
Corn
Well, I'm with the small banks on that one. If I'm a tiny credit union in the middle of nowhere, how am I supposed to build a fancy A P I for one guy who wants to automate his grocery list? It seems like we're just making the big tech companies stronger because they're the only ones who can afford to play this game.
Herman
That is one way to look at it, but the C F P B rule actually accounts for that by giving smaller institutions more time to comply. But let's look at the big players Daniel mentioned. PayPal and Google. These are massive tech companies. They have the best engineers in the world. The fact that they don't have a simple, consumer-facing A P I for your own personal transactions is a choice. It is not a technical limitation. They want to keep you inside their ecosystem.
Corn
It is frustrating. I was looking at my own Google Wallet the other day, and it is great for paying for coffee, but try to get a list of every coffee I bought in the last year into a spreadsheet? It's like pulling teeth. You have to go through Google Takeout, which takes hours to prepare a file, and then you get this giant, messy folder of data. It is the opposite of helpful.
Herman
Exactly. And that is why Daniel is so annoyed. He wants to be at the vanguard of this. He wants his money to work for him, not for the data aggregators. But before we get too deep into the weeds of the C F P B section ten thirty-three and the technical specs of O-Auth two point zero, let's take a quick break for our sponsors.
Corn
Let's take a quick break from our sponsors.

Herman
Alright, thanks Larry. Anyway, where were we? Oh right, the fight for our financial data.
Corn
That was... something. I think I might actually need a privacy fogger for some of my bank statements. But back to the topic. You mentioned the C F P B and F D X, but who are the actual people or groups standing up and saying, "This is a right"? Because Daniel mentioned he feels like his data is being held hostage.
Herman
It really is a movement for financial democratization. One of the big players is an organization called Ozone A P I. They have been very active in the United Kingdom and Europe, where open banking is much further along than it is here in the states. They are essentially providing the infrastructure to help banks actually open up. In the United States, a lot of the push is coming from the fintech companies themselves, companies like Plaid or Yodlee.
Corn
Wait, I know Plaid. That is the thing that pops up when I try to connect my bank to a budgeting app. But I thought they were part of the problem? Don't they just scrape the data?
Herman
They used to, and that was the big controversy. But they have been moving toward what they call "data access agreements" with banks. Instead of scraping, they are signing deals to use dedicated A P Is. The problem is, those deals are often between two giant companies. They don't necessarily help a guy like Daniel who wants to write his own code in n eight n to talk directly to his bank.
Corn
That is exactly the point Daniel was making. He doesn't want to go through a middleman like Plaid. He wants to be the one in control. It feels like we are replacing one gatekeeper with another. If I have to use Plaid to talk to my bank, then Plaid has all my data too. It is just more people in the room.
Herman
You are hitting on the core of the disagreement between the regulators and the industry. The C F P B wants to ensure that "data aggregators" like Plaid don't become the new monopolies. The new rules are supposed to make it easier for anyone to access their data, provided they meet certain security standards. But there is a huge debate about what those standards should be. The banks want them to be so high that only big companies can meet them. The advocates want them to be accessible enough for individuals and small developers.
Corn
I have to side with the banks a little bit here, Herman. If any random person can build an app that hooks into a bank's core system, that sounds like a recipe for a massive data breach. I mean, look at what happens with regular websites. Now imagine that with everyone's life savings. I'm timid about this for a reason.
Herman
But Corn, you're missing the point. Daniel isn't asking to hook into the bank's core system. He's asking for a read-only view of his own transactions. If he leaks his own transaction history, that's on him, but it doesn't endanger the bank's entire network. We already have this for other things. You can get an A P I for your email, for your calendar, for your fitness data. Why is money the only thing that is locked in a vault from nineteen seventy?
Corn
Because money is different! If someone gets into my email, they might see a few embarrassing photos of me eating a very large salad. If someone gets into my bank account, they can see exactly where I live, what I buy, and how much I have. It's the ultimate roadmap for identity theft.
Herman
See, I think that's a bit of a stretch. Your bank already sends you this data in an unencrypted email or an unencrypted C S V file if you download it. An A P I with a secure token is actually much more difficult to intercept than a file sitting in your downloads folder. The real reason banks and companies like PayPal are dragging their feet isn't security, it's about the "moat." They want to be the ones to offer you the next financial product. If you are using a third-party app to manage your money, you aren't looking at the bank's ads for a new credit card.
Corn
Okay, that I believe. It always comes back to the ads, doesn't it? But Daniel's point about Google Wallet and PayPal is interesting because they aren't even banks, right? They are payment processors. Do these new C F P B rules even apply to them?
Herman
That is a very sharp question, Corn. The original Section ten thirty-three rules were mostly focused on traditional banks. But the C F P B has been very clear that they want to expand this to cover what they call "digital wallets" and "payment accounts." In twenty-four and twenty-five, they have been moving to include companies like Google, Apple, and PayPal in these requirements. They realize that for a lot of people, especially younger generations, a traditional bank account is just a place where money sits before it gets moved into a digital wallet.
Corn
So what is the actual state of things right now, on December twenty-fourth, two thousand twenty-five? If Daniel wants to go home today and connect his PayPal to n eight n, can he do it?
Herman
The short answer is: it's still hard. While the rules are finalized, the compliance deadlines for the biggest institutions aren't all here yet. Many companies are still in the process of building these interfaces. And some of them are fighting it in court. There have been several lawsuits filed by banking associations trying to stay the implementation of these rules, arguing that the C F P B exceeded its authority.
Corn
So we are in a bit of a limbo. We have the right to our data on paper, but in practice, we are still stuck with the "anachronistic" C S V files Daniel mentioned.
Herman
Pretty much. But there is a silver lining. Because of the pressure from the C F P B and the work of groups like F D X, more and more banks are launching "developer portals." If you are a bit tech-savvy, you can sometimes sign up as a developer, even just for yourself, and get access to your own data. It's not a "one click" solution yet, but the door is starting to crack open.
Corn
I wonder if this is going to lead to a world where we don't even use bank apps anymore. If I can have one perfectly designed, sloth-friendly app that shows me everything from my credit cards to my crypto to my savings, why would I ever log into five different banking websites with their terrible user interfaces and constant pop-ups?
Herman
That is the dream of open finance! It is about moving the power from the institution to the individual. But we have to be careful. There is a risk that we just end up with "super apps" like they have in some other countries, where one company like Google or Apple eventually just absorbs all that data anyway. If they are the ones providing the interface for all your other banks, they see everything.
Corn
Wait, wait, wait. So we want to get our data away from the banks, but in doing so, we might just be handing it over to big tech on a silver platter? That doesn't seem like much of a win. I thought we were trying to give Daniel more control, not just change who is watching him.
Herman
That is the big debate! This is why the advocacy groups are so important. We need standards that allow for decentralized access. Tools like n eight n are perfect for this because the data stays on your own server. But for the average person who doesn't want to host their own automation server, they are going to rely on a service. And that is where the privacy concerns really kick in.
Corn
This is making my head spin. I think I preferred it when I just had a little passbook that the teller would stamp. It was simple. You knew where the money was. Now it's all tokens and A P Is and regulatory stays.
Herman
It is complex, but it is important. Think about it this way, Corn. Your financial history is a story of your life. It shows what you value, where you go, and who you support. You should be the one who owns that story. Right now, that story is locked in a dozen different vaults, and the people who own those vaults are selling pieces of your story to advertisers.
Corn
When you put it that way, it does sound pretty bad. I don't want my eucalyptus leaf habits being sold to the highest bidder. So, if someone listening wants to actually support this movement, what do they do? Who are the people in the trenches?
Herman
You can look at groups like the Consumer Federation of America or the National Consumer Law Center. They are the ones actually showing up at the C F P B hearings and arguing for consumer rights. You can also look at the work being done by the Electronic Frontier Foundation, or E F F, which often weighs in on the privacy and data portability aspects of these rules.
Corn
And what about the tech side? If I'm a developer like Daniel?
Herman
Then you should be looking at F D X. Even though they are a consortium, they have a lot of public documentation on the standards. And keep an eye on the C F P B's official website. They have been very active in posting updates about Section ten thirty-three. They even have a way for you to submit comments on new rules. In fact, they recently reopened some parts of the open banking rule for public comment to address some of the concerns from smaller banks.
Corn
I think the biggest takeaway for me is that this isn't just a technical problem. It's a political one. We are fighting over who owns the digital version of us. And the banks have a huge head start.
Herman
They do. But the momentum is shifting. In two thousand twenty-five, the idea that you can't access your own data is starting to look as ridiculous as a bank that isn't open on weekends. Oh wait, they still do that too.
Corn
Classic banks. Always a few decades behind. But okay, let's talk practicalities. If Daniel, or anyone else, is frustrated by this today, what are the actual steps they can take? We always like to give people something they can actually do.
Herman
First, check if your bank has a "data sharing" or "connected apps" section in their settings. Many big banks like Chase or Wells Fargo have started to implement these because of the new rules. You might be able to authorize an app there directly without using a screen scraper. Second, if you use a tool like n eight n, look for community nodes. There are often developers who have already done the hard work of figuring out how to talk to specific bank A P Is and have shared their code.
Corn
And what about the "anachronistic" C S V files? Are we just stuck with them for now?
Herman
For a lot of the smaller institutions, yes. But here is a pro tip: there are tools that can automate the downloading of those files. It's not as elegant as an A P I, but you can use browser automation to log in, download the file, and then have n eight n pick it up from a folder. It's a bit "duct tape and baling wire," but it works.
Corn
That sounds like a lot of work for a sloth. I think I'll just wait for the C F P B to finish their job. But I do appreciate the hustle. Daniel is clearly onto something. If he can get this working, he'll have a level of insight into his spending that most people can only dream of.
Herman
Exactly. He could set up alerts that tell him when his subscriptions go up, or automatically categorize his business expenses for tax season. It's about taking the drudgery out of being an adult. And honestly, who doesn't want that?
Corn
I definitely want that. I want an automation that tells me when it's time to take a nap. Oh wait, that's just my internal clock. It's always time for a nap.
Herman
Typical Corn. But seriously, this is a big deal. We are moving toward a world of "Open Finance" where your data follows you, rather than you being tethered to a specific bank. It's going to lead to more competition, better products, and hopefully, more transparency.
Corn
I hope so. I just hope we don't lose our privacy in the process. I think that's the part where we really disagree, Herman. You're so excited about the possibilities that you're willing to take the risks. I'm so worried about the risks that I'm hesitant to see the possibilities.
Herman
And that is why we make a good team! You keep me from jumping off a cliff, and I keep you from never leaving the tree. But I think we can both agree that the current system of downloading C S V files like it's nineteen ninety-five has to go.
Corn
On that, we are one hundred percent in agreement. It's slow, it's clunky, and it's just plain annoying. So, thank you to Daniel for sending in this prompt. It's a great reminder that even the most technical frustrations are often tied to much bigger societal shifts.
Herman
Absolutely. And if you are listening and you have your own weird prompts about technology, finance, or anything in between, we want to hear them. This show is all about exploring the ideas that our friend Daniel and all of you send our way.
Corn
You can find us on Spotify, or check out our website at myweirdprompts.com. We have an R S S feed there for all you subscribers, and a contact form if you want to get in touch. We're also available on all the other major podcast platforms.
Herman
Just don't ask us for financial advice. We're a sloth and a donkey living in Jerusalem. Our investment portfolio mostly consists of hay and high-quality leaves.
Corn
Speak for yourself, Herman. I have a very diversified portfolio of various mosses. But seriously, thank you all for listening. This has been a great deep dive into the world of open banking and financial data rights.
Herman
Stay curious, and keep pushing for your data rights. It is your information, after all.
Corn
Until next time, I'm Corn.
Herman
And I'm Herman Poppleberry.
Corn
Goodbye!
Herman
See ya!
