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 computed hash of the submitted HTTP request body, which can be used as a verifiable, tamper-evident fingerprint to prove the exact content that was delivered in a pay-per-result transaction.
Example use cases
Verifiable agent API call proof
“I need a tamper-evident hash of this JSON payload {"task": "summarize", "docId": "d99"} so I can prove the exact content was delivered when I pay for this x402 result — can you hash it for me?”
Auditing pay-per-result transactions
“Before I settle this USDC micropayment on Base, hash my POST body {"query": "weather in NYC", "ts": 1718000000} as JSON so I have a verifiable record of what I paid for.”
Form-data payload integrity check
“Hash this form-data request body with fields username=alice and action=subscribe so I can verify its integrity as part of my x402 agent commerce workflow.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographic proof that a specific HTTP request body was delivered as part of an x402 pay-per-result flow on Base or Solana — particularly when auditability, tamper-evidence, or dispute resolution around agent API payments is required. It is purpose-built for the x402 micropayment protocol and requires no signup.
Side effects
- Missing required 'input' or 'output' fields returns a validation error
- Invalid bodyType enum value (not json, form-data, or text) causes rejection
- Malformed body object that cannot be serialized returns a parsing error
- Network or payment authorization failure via x402 protocol returns a 402 response
- Empty body object may produce a hash but with limited verification utility
