Request Body

Responses

200OK

400`nonce and expiry are required with agent_sig`; `commitment expired` (restart at step 1); `invalid nonce: must be 0x-prefixed 32-byte hex` (the decimal form was echoed); `invalid agent_sig: must be 0x-prefixed 65-byte hex`; `recover signer: …`.

401Request-auth error.

403The recovered signer is not `ownerOf(reviewer_agent_id)`.

404`ownerOf` reverted for a genuinely nonexistent token. `404` and `500` split the same lookup: a nonexistent agent is a `404`, an RPC failure while reading a real one is a `500`. Retry the second, fix the first.

500A transient RPC failure resolving the owner, or the write failed.
