Knox Anchor

Given a SHA-256 anchor hash (64 hex chars), return the anchor record, chain link validity (predecessor present and matched), event type, sequence number, and verify URL. Public — no authentication required.

Anchor a generic agent action to the Knox chain. Accepts any event_type from the canonical taxonomy plus a payload object. Returns the anchor sequence, payload hash, predecessor hash, timestamp, and verify URL. Requires a Knox Bearer API key on the Authorization header (a public-demo key is auto-provisioned for unauthenticated callers, rate-limited at the free tier).

Convenience anchor for the AAM Model Context Protocol theater. Records an `agent_mcp_tool_call` event with structured tool-call metadata (server URL, tool name, argument digest, agent identity, response digest). Use this to make an MCP-using agent's actions independently auditable.

Anchor a SHA-256 file digest to Knox and return an affidavit architected for FRE 902(13)/(14) self-authentication. The file itself is not transmitted — the caller computes the hash and only the digest + filename + size + MIME type are anchored. Admissibility in any matter remains a determination of the presiding court. Public — no authentication required (rate-limited at the public-demo free tier).
