Delx Commerce Record Fingerprint
x402
Delx Commerce Record Fingerprint is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Computes a deterministic SHA-256 fingerprint of a JSON record using sorted keys and compact separators for verifiable, canonical hashing.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the schema identifier (delx/util-record-fingerprint/v1), the hashing algorithm used (sha256), the computed hex fingerprint string, and a description of the canonicalization method (sorted JSON keys, compact separators, default string conversion).
Example use cases
Tamper detection for agent outputs
“Take this JSON result my data pipeline produced and give me a SHA-256 fingerprint so I can store it alongside the record and verify it hasn't been altered later: {"order_id": "ORD-8821", "status": "shipped", "timestamp": "2024-06-01T10:00:00Z"}.”
Deduplication key for event records
“I'm getting duplicate events from my webhook and need a stable canonical hash to deduplicate them — fingerprint this event object for me: {"event": "user_signup", "email": "alice@example.com", "ts": 1717200000}.”
Audit trail integrity proof
“Before I archive this audit log entry, generate a canonical SHA-256 fingerprint of it so I can put it in an immutable log as a proof of the record's content: {"actor": "admin", "action": "delete_user", "target": "user_99", "reason": "GDPR request"}.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/record-fingerprint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, canonical, and verifiable SHA-256 fingerprint of a JSON record without setting up your own hashing infrastructure. It is ideal for agents that need tamper detection, deduplication keys, or audit trail proofs in a pay-per-use model with no signup required. Prefer it over local hashing when you need a standardized canonicalization scheme (sorted keys, compact separators) that is reproducible across systems and languages.
Side effects
- Missing or null 'record' field returns a validation error
- Non-serializable input values (e.g. circular references) may cause a processing error
- Payment failure via x402 results in a 402 Payment Required response before processing
- Malformed JSON body returns a 400 Bad Request
- Network timeout on the Base/Solana payment rails delays response
