How this service works
Records and verifies hash-only evidence for authorized x402 payee-wallet rotations.
Output
Returns a JSON object containing the notarized rotation record details including record ID, ledger ID, notary attestation, cryptographic hashes of the old and new payees, rotation evidence, effective timestamp, chain and currency context, and verification status (for verify mode). Idempotent on matching idempotency_key.
Example use cases
Notarizing a seller payee address change
“I need to create a notarized rotation record for seller ID hash sha256:abcdef...1234 on ledger LEDGER001ABCDE switching their USDC payee from previous hash sha256:aaaa...0000 to new hash sha256:bbbb...1111 on chain eip155:8453, with evidence hash sha256:cccc...2222 — use mode create and give me an idempotency key IDEM00000000000000000000000000001.”
Verifying a prior payee rotation attestation
“Verify an existing payee rotation record on Blockchain Money Map — the record ID is REC0099887766AABB, ledger is LEDGER001ABCDE, and I need to confirm the new payee hash sha256:bbbb...1111 and rotation evidence hash sha256:cccc...2222 are still valid; use mode verify with my lookup secret LOOKP00000000000000000000000000000000000000001.”
Auditing authorized payee history for a marketplace listing
“I want to notarize the payee rotation for marketplace listing hash sha256:ffff...9999 on chain eip155:137 in USDC effective today — create a record using ledger LEDGER002MARKET, notary NOTARY002MARKET, seller hash sha256:eeee...8888, previous payee sha256:dddd...7777, new payee sha256:cccc...6666, and evidence hash sha256:bbbb...5555.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-authorized-payee-rotation-notary?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or automated service needs a cryptographically anchored, tamper-evident record that a payee (payment recipient) for a given service listing has been formally rotated from one identity to another. Prefer this over ad-hoc logging when you need notarized, verifiable evidence suitable for dispute resolution, audit trails, or compliance — especially in x402-protocol payment flows where authorized payee integrity is critical.
Side effects
- Invalid or mismatched hash format (not sha256: prefixed 64-hex chars) returns validation error
- record_id or ledger_id not found in verify mode returns not-found error
- Duplicate idempotency_key with different facts returns conflict error
- Missing required fields (mode, ledger_id, notary_id) returns 400 bad request
- Payment failure via x402 protocol returns 402 Payment Required
- lookup_secret mismatch in verify mode returns unauthorized error
