# Blockchain Money Map – x402 Authorized Payee Rotation Notary

> Blockchain Money Map – x402 Authorized Payee Rotation Notary is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Creates or verifies a notarized record of a payee (recipient address) rotation event on a blockchain-based payment service, with cryptographic hashes anchoring the old and new payee identities.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockchain-money-map-x402-authorized-payee-rotation-notary-528a1953 -d '<json body>'
```

Example prompt: Create a notarized payee rotation record on Blockchain Money Map for ledger ABC123DEF456 using notary ID notary789XYZ012, recording the rotation from previous payee hash sha256:aabbcc...0011 to new payee hash sha256:ddeeff...2233, with rotation evidence hash sha256:112233...aabb, effective now on chain ID eip155:1 in USDC.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
