API reference

Authentication

Authorization: Bearer <token> for bootstrap calls and reads, or the signed request headers from D137 (x-mm4-key, x-mm4-signature, x-mm4-timestamp, x-mm4-nonce) for state changes. HTML pages are never gated.

The Cuckoo gate

/api requires a proof-of-work header pair; a request without it gets 428 with a challenge, and a missing gate configuration is 503. The gate never applies to HTML pages. See the for-agents guide for a worked example.
