Developers

Move money with a few lines of code.

A predictable REST API, typed SDKs, an MCP server and a sandbox that behaves like production, for every product: accounts, collections, payouts and cards.

MCP server

A controlled wallet for any assistant

The assistant never sees your live keys or your balance. It only gets what the agent's policy allows.

Sandbox

Test every scenario before going live

With a sk_test_ key, magic values trigger specific outcomes. No real card is issued and no real funds move.

Errors

Errors that people and agents can act on

Every decline returns a stable code and a readable message, so your code or your agent knows whether to retry, ask for less or stop.
