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 the input object is complete (true/false), a list of any missing required fields, the operation status ('pass' or 'fail'), an SHA-256 hash of the input for verifiable audit, and a flag confirming no data was retained and no external calls were made.
Example use cases
Validate API response completeness
“I just got a response from the payments API. Can you check if it includes all the required fields — 'transaction_id', 'amount', 'currency', 'status', and 'timestamp' — and tell me which ones are missing?”
Form submission data audit
“Before I save this user registration form data, check if the object has all required fields: 'first_name', 'last_name', 'email', 'phone', and 'date_of_birth'. Here's the submitted object: {"first_name": "Bob", "email": "bob@test.com", "phone": "555-1234"}.”
ETL pipeline record check
“I'm processing incoming records from a data feed and I need to make sure each one has 'product_id', 'sku', 'price', 'stock_quantity', and 'category' before I load them. Can you run the required-fields check on this record: {"product_id": "P123", "price": 19.99, "category": "electronics"}?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-required-fields-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup validation of JSON object completeness with cryptographic evidence (SHA-256 input hash) confirming no data retention. It is ideal for agents that process untrusted or sensitive payloads and need verifiable, auditable validation without standing up infrastructure. Prefer it over custom code or heavier schema validators when cost predictability ($0.001 USDC per call), zero data retention guarantees, and in-memory processing matter.
