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 with a top-level 'result' containing 'passed' (boolean) and 'invalid_fields' (array of field names that failed validation), a 'status' string ('pass' or otherwise), and an 'evidence' object including a SHA-256 hash of the input, a flag confirming no data retention, and a count of external calls made (always 0).
Example use cases
User registration form validation
“I have a user signup payload — {"name":"John","email":"john@@bad","recovery":"john.doe@gmail.com"} — can you check whether the fields "email" and "recovery" contain valid email addresses before I store the record?”
CRM data quality audit
“I'm processing a contact record from our CRM: {"primary_email":"sales@acme.com","secondary":"not-valid","billing":"ar@acme.co"} — validate the fields ["primary_email","secondary","billing"] and tell me which ones fail the email format check.”
API response email field sanity check
“Before I forward this API response to the next step in my pipeline, verify that the email fields ["from_address","reply_to"] in this object {"from_address":"noreply@service","reply_to":"support@company.io","id":"abc123"} are properly formatted.”
