# AgentBank Partner API

> Build regulated fiat and crypto payments for your own end users.

The Partner API lets your backend offer payments to verified end users:
fiat to crypto (on-ramp), crypto to fiat (off-ramp), or fiat to fiat through
an intermediate crypto asset. You provide the final recipient; AgentBank
handles routing and returns the funding instruction and payment state.

Partner requests use your merchant Ed25519 key. The separate portal API uses
a JWT for webhook management and payment-history reads. Keep all credentials
in your trusted backend.
