API reference

Every operator-facing endpoint with its exact request and response schema, generated live from GET /v1/openapi.json — the same schemas the server validates against. Signing, the seamless wallet and webhooks are explained step by step in the integration guide.

Sandbox: https://api.urbanrats.com. Signed endpoints need the four x-ur-* headers (Ed25519 or HMAC-SHA256 key). Unknown fields are rejected. Error bodies are {code, message, correlationId}.
