How to Connect AI to Your Bank Account (So It Tracks Your Money For You)

Here's a sentence that would have sounded ridiculous five years ago: you can now ask an AI assistant how much you spent on groceries last week and get an exact answer from your actual bank data, in seconds.

No logging into your banking app. No scrolling through transactions. No adding things up in a spreadsheet. You just ask.

Here's exactly how to set it up, using Up Bank's free API and an AI assistant called OpenClaw. We'll walk through getting the API key, connecting it, and what you can actually do once it's running.

Why Up Bank?

Most Australian banks don't offer public API access — or if they do, it's restricted, expensive, or buried behind corporate onboarding processes. Up Bank is the exception. They built a full public API, it's free, and it gives you access to your transaction history, account balances, categories, and more. If you're serious about connecting your bank to an AI assistant, Up is the obvious starting point.

What you need before you start

• An Up Bank account (personal or business)
• A device that can run OpenClaw (a Mac, PC, or a always-on server)
• About 20 minutes to set it up the first time

The setup is a one-time thing. Once it's running, it stays running.

Step 1: Get your Up Bank API key

Head to developer.up.com.au and sign in with your Up Bank credentials. Once you're in, navigate to your dashboard and create a new API key.

Give it a name — something like "OpenClaw Assistant" or "Home AI" — so you remember what it's for. The Up Bank API is read-only by design — there's no write access to configure, so you don't need to worry about permissions. Reading your transactions is all you need for the useful stuff.

Copy the API key and store it somewhere safe. It looks like a long string of random characters. Treat it like a password — don't share it publicly, don't put it in a GitHub repo, don't email it.

Step 2: Save the API key in your credentials folder

OpenClaw uses a credentials folder to store sensitive keys. Create a file called up.txt in your OpenClaw credentials folder and save your API key there. The format is:

up:yeah:YOUR-API-KEY-HERE

Replace YOUR-API-KEY-HERE with the key you got from Up Bank. Save the file.

The up:yeah: part tells OpenClaw which service this key is for — you don't need to change it.

Step 3: Tell OpenClaw to connect

Once the API key is saved, just send OpenClaw a message like this:

You: Hey OpenClaw, I've added my Up Bank API key to the credentials folder. Please connect to my Up Bank account using the API at developer.up.com.au. Use my timezone and set purchases to use createdAt (not settledAt) so "what I spent today" reflects when I actually bought something.

That's it. OpenClaw will read the API key, connect to your Up Bank account, and start answering questions about your spending. You don't need to configure anything or find account IDs — it handles all of that automatically.

Step 4: Start asking questions

Once everything is connected, you can ask your AI assistant natural questions about your money. Here are the kinds of things you can set up:

"How much have I spent today?"

Get an instant breakdown of today's spending, grouped by merchant and category. No app logging, no adding up receipts. It reads your actual transactions from your Spending account and ignores transfers between your own accounts.

"Can I afford a $500 holiday?"

By default, OpenClaw checks your Spending account balance. But you can teach it to look at specific Savers too — tell it once, and it remembers. So if you want it to check your Splurge saver before saying yes or no, just say so:

You: Can I afford a $500 holiday? I use my Splurge saver for fun purchases.

AI: Got it — I'll check your Splurge saver for fun purchases. I can afford it:
  Splurge balance: $350.00
  Short by: $150.00
  📅 I'll set a reminder — ping you in 30 days to re-check.
  💡 Save ~$5/day for 30 days and you'll have it.

OpenClaw remembers your preferences, so you don't have to repeat "use my Splurge saver" every time. Just tell it once.

"Show me my balance"

A full table of every Up account you have — Spending, all your Savers, Business — with current balances. Much faster than logging into the app.

"What's my weekly spending summary?"

A week-in-review showing total spent, top merchants, top categories, and a category breakdown. Good for noticing patterns ("I spent $400 on food delivery this week — maybe I should cook more").

"Do I have any bills coming up?"

Scans your last few weeks of transaction history and detects recurring payments — subscriptions, insurance, rent, utilities — so you know what's hitting your account and when.

"Set up a daily spending digest"

You can schedule a daily message — every evening at 8pm, for example — that automatically sends you a summary of the day's spending, how much went into your Savers, and your current balance. No need to ask for it, it just arrives.

What the setup looks like in practice

Once the API key is saved and OpenClaw knows your account IDs, the conversation with your AI assistant looks something like this:

You: how much have i spent today
AI: 💸 Spent today: $44.06 (5 transactions)
  CarePark — $16.39
  Coles — $14.70
  ALDI — $8.97
  7-Eleven — $4.00

You: can i afford $800 for a new monitor
AI: ❌ Can't afford it right now.
  Spending balance: $224.52
  Short by: $575.48

  🛒 for 'new monitor'
  📅 I'll set a reminder — ping you in 30 days to re-check.
  💡 Save ~$19/day for 30 days and you'll have it.

If you can't afford it, just ask "set a 30-day reminder" and it will — the AI will ping you again in a month to re-check.

Is this safe?

Worth addressing directly. You're giving an AI assistant access to your bank data. Here's the honest picture:

• Read-only access. With a read-only API key, the AI can see your transactions and balances but cannot move money, make payments, or change anything. Think of it like a bank statement — you can read it, but you can't do anything with it.
• Your API key is a gatekeeper. Without it, nothing can access your data. Keep it as safe as you'd keep a password.
• The AI doesn't "remember" your data. It queries the API each time you ask something, so it always sees the current state — not a cached version that could go stale.
• OpenClaw runs on your own machine. Unlike some cloud-based AI tools, OpenClaw processes locally. Your credentials and data stay on your own infrastructure.

The main risk is the same as any online banking — someone getting hold of your API key. Use common sense: don't share it, don't paste it in public chats, store it in the credentials folder as described.

What you can't do (and why that's fine)

The Up Bank API is read-only in its current form. You can't use it to:

• Automatically pay bills or transfer money (which is probably what you'd want, eventually, but that's a bigger automation project)
• Open new accounts or change account settings
• Initiate payments to other people

For the use cases that matter most — tracking spending, checking balances, setting spend alerts, detecting bills — read-only access is all you need. You don't actually want an AI moving your money around without your involvement anyway.

Making it more powerful over time

The setup described here is the foundation. Once it's running, you can build on it:

• Add bill detection alerts — get a Telegram message the moment a new recurring payment appears in your account
• Track savings goals — connect your Saver accounts and ask "how much longer until my $5k car fund is full?"
• Weekly summaries to Telegram — every Monday morning, a full spending report lands in your messages
• Income tracking — detect when payday arrives and track how much is coming in vs going out
• Splurge monitoring — have a specific "Splurge" account that you ask about before any non-essential purchase

The AI doesn't forget. It doesn't get tired. And it can cross-reference your full transaction history in a way that no human could do manually in a reasonable time.

The Up Bank API — what developers think

For context: Up Bank's API is genuinely well-built. It's REST-based, uses standard authentication (Bearer tokens), returns clean JSON, and has sensible rate limits for personal use. The documentation at developer.up.com.au is straightforward and includes code examples in Ruby, Python, PHP, and Go. If you wanted to build your own tools on top of it — a custom dashboard, a Notion integration, automated reports — the API makes that possible.

The fact that Up offers this for free, with no personal account fees and no transaction fees, makes them stand out significantly compared to the major banks, most of which either don't have public APIs or charge for access.
