Every endpoint under /api/v1 is documented in the pages in this section, each with its parameters, request body, response schema, and a Try it playground you can call with your own key.

​
Before you start

Authenticate

Send Authorization: Bearer murmo_... on every request. Paste your key into the playground’s Authorization field to make live calls.

Money is strings

Every monetary value — in and out — is a full-precision decimal string. Never a number, never raw base units, never scientific notation.

Conventions

  • Envelope — every success is wrapped as { "data": ... }. The shape inside data varies by endpoint (array, keyed object, single resource, or null); see Groups & proposals → Response envelopes.
  • Errors — every error returns one consistent envelope: { statusCode, code, message, errorId }, plus retryable / details when applicable. Branch on the stable code. See Errors.
  • Rate limit — 1,200 requests / 60 seconds per key. See Rate limits.
