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 indicating whether all enum fields passed validation (passed: true/false), a list of invalid_fields (empty array if all pass), a status string ('pass' or 'fail'), an operation identifier, and evidence metadata including whether input was retained (always false), the SHA-256 hash of the input, and the number of external calls made (always 0 — processed in memory).
Example use cases
API payload validation before processing
“Before I store this incoming API payload, check that its enum fields are valid — enums are {priority: ['low','medium','high'], state: ['open','closed','archived']}, and the object is {priority: 'urgent', state: 'open', id: 42}.”
Form submission enum compliance check
“I have a form submission with these enums: {gender: ['male','female','nonbinary','prefer_not_to_say'], subscription: ['free','pro','enterprise']} — can you verify that this object is compliant: {gender: 'female', subscription: 'premium', age: 28}?”
Data pipeline quality gate
“Run an enum fields check on this batch record before it enters our pipeline — enums: {region: ['us','eu','apac'], tier: ['1','2','3']}, object: {region: 'latam', tier: '2', volume: 500}.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-enum-fields-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup enum field validator for JSON objects — particularly in agentic pipelines where you want verifiable, tamper-evident validation with a SHA-256 input hash and a guaranteed no-retention policy. Prefer this over building custom enum validation logic when you need an auditable, external validation step that produces a structured pass/fail result with evidence metadata, especially in USDC-native micropayment workflows via the x402 protocol.
Side effects
- Malformed JSON input causing parse errors
- Object or enums exceeding 128 properties (maxProperties limit)
- Missing or null required fields returning validation errors
- Unexpected enum key mismatches if enums object keys don't match object keys
- Network or payment processing errors returning HTTP 402 or 5xx
