Delx Record Fingerprint
x402
Delx Record Fingerprint is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

How this service works
Create a stable SHA-256 fingerprint from canonical JSON. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production co…
Output
Returns a machine-readable JSON object containing the deterministic SHA-256 fingerprint of the input record. The result is stateless and advisory — no data is retained after execution.
Example use cases
Deduplication preflight in data pipeline
“Before inserting this customer record into the database, generate a SHA-256 fingerprint for it so I can check if we've already processed it: {"customerId":"C-9912","name":"Acme Corp","tier":"enterprise"}.”
Policy change detection audit
“Fingerprint this policy JSON so I can compare it against last week's version and flag any tampering: {"policyId":"P-44","rules":["no-external-egress","require-mfa"],"version":2}.”
Cache key generation for API responses
“I need a deterministic cache key for this canonical JSON payload — can you compute a SHA-256 fingerprint for it? {"endpoint":"/pricing","market":"US","tier":"pro","currency":"USD"}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/record-fingerprintWhen to prefer
Choose this endpoint when you need a fast, stateless, deterministic SHA-256 fingerprint of a JSON record with no data retention — ideal for preflight deduplication, cache key generation, tamper detection, or audit logging inside enterprise agent workflows. Prefer it over general-purpose hashing libraries when you need a pay-per-call, infrastructure-free solution that integrates directly into an agent pipeline via x402.
Side effects
- Empty or null record object causes validation error
- Non-serializable or circular JSON object may fail canonicalization
- Malformed input schema returns a 4xx error
- Upstream payment failure (x402) blocks execution and returns payment-required error
