How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON object containing the ledger operation outcome: for 'fingerprint' mode, the stored record ID and hash confirmation; for 'compare' mode, a diff report showing which facts changed between current and reference; for 'verify' mode, a pass/fail stability status with details on any mismatched fields.
Example use cases
Baseline fingerprint for new MCP tool
“Create a fingerprint record for my MCP tool 'transaction-decode' — it uses method POST, route /api/x402/tx-decode, operation ID 'decode-tx-v1', input schema hash sha256:1a2b3c...9f0e1d, output schema hash sha256:4d5e6f...2a3b4c — store it in ledger 'prod-agent-ledger-2024' with standard retention.”
Verify operation hasn't drifted
“Verify that the MCP tool 'wallet-intel' at route /api/x402/wallet-intel still matches the record I stored earlier — use record ID 'rec-wallet-intel-v2-abc123xyz' in ledger 'prod-agent-ledger-2024' and check it against current resource hash sha256:deadbeef...cafebabe.”
Compare two operation versions
“Compare the current version of my 'batch-wallet-screen' MCP tool against the reference facts I registered last month — the new input schema hash is sha256:111aaa...999fff and the reference route was POST /api/x402/batch-wallet-screen — use ledger 'staging-ledger-xyz987' and tell me what drifted.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-mcp-operation-stability-ledgerWhen to prefer
Use this endpoint when you need to track schema stability and detect drift in MCP tool definitions over time — especially in agent fleets where API contracts must remain consistent. It is the right choice when you want tamper-evident, ledger-backed fingerprinting of API operation facts (route, schema hashes, payment metadata) rather than simple in-memory version checks. Prefer this over generic versioning systems when you need an auditable, paid notarization record with retention policies.
Side effects
- Invalid mode enum value returns 400 with validation error
- Malformed SHA-256 hash pattern causes schema rejection
- ledger_id or record_id not found returns 404
- lookup_secret mismatch returns 403 forbidden
- Duplicate idempotency_key with conflicting payload returns conflict error
- Missing required facts fields for the chosen mode causes partial processing error
- Payment not received (x402) results in 402 Payment Required response
