Key takeaways
Wallbit for Agents lets you automate finances through code.
It requires an API Key in the X-API-Key header for every request.
Errors use standard HTTP status codes.
If you exceed the rate limit, the API returns a 429 response.
At Wallbit, we offer our customers a borderless financial experience. But borders are no longer just geographical, they’re also programmatic.
That’s why we launched the first tool that gives you full programmatic control over your finances: Wallbit´s Public API, called Wallbit for Agents. With it, you can build your own interfaces and workflows, automate your investment strategies, and connect your finances to AI agents.
What is Wallbit for Agents?
Wallbit for Agents is the Wallbit public API. An infrastructure layer that lets you interact with your Wallbit account through code. Instead of manually navigating the app to check balances or buy stocks, you can use commands and scripts to execute these actions automatically and in a customized way.
It’s the ideal tool for users who want to:
Build custom interfaces. Design your own dashboards or mobile apps tailored to your workflow.
Automate investments. Schedule stock, ETF, or bond purchases and sales based on specific parameters or market signals.
Integrate AI agents. Connect your account with tools like Claude Code, Cursor, or v0 so intelligent assistants can manage your finances, rebalance your portfolio, or monitor your expenses for you.
What can you do with the Wallbit API?
For years, financial management was limited to static apps and manual processes. The Wallbit Public API aims to remove those limitations so you can design a financial experience tailored to your needs.
The tool includes a range of features designed to optimize processes:
Real-time balance checks. Access your U.S. bank account balance and available investment funds. Create categories and logic that fit your workflow exactly.
Investment management. Execute buy and sell orders for stocks (such as AAPL, TSLA, etc.) and view your full portfolio. Schedule savings, investments, and transfers to run autonomously.
Transaction history. View all your transactions and cash flows in detail with filtering options. Monitor balances, cash flow, and portfolio performance instantly.
Crypto asset control. Manage cryptocurrency wallet operations programmatically.
Smart monitoring. Set up custom alerts based on asset behavior and AI-powered financial signals.
AI assistant integration is also part of the offering: you can configure your agents to monitor balances and operate on your behalf. It’s compatible with the most modern development tools in the ecosystem:
Cursor and Claude Code
Lovable and v0
How to get started with the Wallbit API
Follow these steps to activate your access:
Request your API key. Go to developer.wallbit.io and request your API Key. You’ll receive an invitation with instructions to generate your access credentials.
Configure your environment. The API uses secure authentication through HTTP headers. You must include your key in every request under the X-API-Key.
Make your first request. You can start with a simple query to view your stock portfolio using the balance endpoint:
GET https://api.wallbit.io/api/public/v1/balance/stocksExplore the documentation. Visit our full technical documentation to discover all available endpoints, curl code examples, and boilerplates to start building immediately.
Security and privacy
Your security is our priority. The API uses end-to-end encryption standards and robust authentication protocols.
It’s important to remember that:
Keys are personal. Each user generates their own access credentials.
Full control. You decide which permissions to grant and which tools to connect to your account.
Institutional protection. Your funds and assets remain protected by the same security standards and regulations as a standard Wallbit account, including SIPC protection for your investments.
Frequently Asked Questions
1. What does a 429 “Too Many Requests” API error mean?
The HTTP 429 status code indicates that the API request limit has been exceeded within a given time period. When this happens, the system temporarily blocks new requests to prevent overload and ensure fair usage across all users.
2. What is an API Key and what is it used for in a financial integration?
An API Key is a unique credential that identifies and authorizes a user or application to interact with an API. In Wallbit, this key must be sent in the X-API-Key header with every request to validate access and protect the account from unauthorized connections.
3. What are HTTP status codes and why are they important in an API?
HTTP status codes are standard responses that indicate the result of each request sent to an API. For example, a 200 status code confirms that the operation was successful, while codes such as 401 or 403 indicate authentication or permission issues. Understanding these codes helps developers debug integrations and automations more efficiently.
