Ship AI products that can actually move money.
Tamarind is the Open Banking and payments layer for AI assistants, agents, and apps. Integrate once. Stay out of regulation. Let your users do more than just talk to their money.
AI products hit a wall at the bank.
AI assistants and agents have gotten remarkably capable. But the moment a user wants to do something financial — check a balance, split a bill, pay a freelancer, move money between pots — the experience breaks.
Today's options are bad. Screen-scraping is fragile and forbidden. Building Open Banking in-house takes twelve months and FCA permissions you don't want to own. Embedded finance providers were built for apps, not for AI.
The result: every AI product on the market is blind and powerless the moment money matters.
One API. Open Banking and payments, built for AI.
Tamarind gives your AI product secure, regulated access to account information and payment initiation across UK banks. We handle the FCA permissions, the bank integrations, the auth flows, and the user consent.
Your assistant gets clean, structured access to real balances, transactions, and payment rails — through an interface designed for how AI actually works: tool calls, structured responses, scoped permissions, human-in-the-loop approval.
You stay out of regulation. Your users stay in control.
Three primitives. Drop them into any assistant.
Account Information
Real-time access to balances, transactions, and account metadata across UK banks. Your AI can finally answer “can I afford this?” with the same context a human would have.
Payment Initiation
Your AI proposes a payment — your user approves it in their bank app, the same way they would any transfer. Tamarind never touches the funds. No custody, no liability, no surprises.
Built for Agents
Designed around the patterns AI products actually use: tool definitions, structured outputs, granular consent, audit trails. Drop it into your assistant in an afternoon.
If you're building any of these, we'd like to talk.
AI Assistants & Agents
Consumer assistants that want to handle money tasks alongside everything else.
Fintech Products
Apps adding AI features that need real financial context to be useful.
Enterprise & Platforms
Teams embedding AI into financial workflows where accuracy and compliance matter.
What teams ask us.
- Do I need FCA authorisation to use Tamarind?
- No. Tamarind holds the FCA permissions. You integrate once through our API and your AI product gains regulated access to Open Banking rails without needing your own authorisation. We handle compliance, bank connections, and user consent flows.
- How does it work for AI agents and tool calls?
- Tamarind is designed around how AI actually works: tool definitions, structured JSON responses, scoped permissions, and human-in-the-loop approval. Your assistant calls a tool; Tamarind returns clean account data or initiates a payment that the user approves in their bank app.
- What does 'no custody' mean?
- Tamarind never holds, stores, or moves user funds directly. When a payment is initiated, the user approves it in their own bank app through the standard authorisation flow. The bank executes the payment — not Tamarind.
- How quickly can we integrate?
- The API is designed to drop into an existing AI assistant in an afternoon. Early access partners get hands-on integration support from the Tamarind team.

We're working with a small number of teams ahead of GA. Early partners get hands-on integration support, input on the roadmap, and preferential pricing at launch.
