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 values of both compared fields, a boolean 'matched' flag indicating equality, the operation status ('pass' or 'fail'), and an evidence block with a SHA-256 hash of the input, confirmation that no data was retained, and the count of external calls made (always 0), enabling verifiable, auditable comparisons.
Example use cases
Payment reconciliation field check
“I have a payment record JSON like {"charged": 99.99, "authorized": 99.99, "customer": "jane"} — can you verify that the 'charged' and 'authorized' fields are exactly equal and return proof?”
Form submission consistency check
“In this form submission object {"email": "alice@example.com", "confirm_email": "alice@example.com"}, check whether the 'email' and 'confirm_email' fields match, and give me a verifiable result I can log.”
Data pipeline integrity validation
“I'm running a data pipeline and I have a record {"source_count": 1500, "destination_count": 1500, "batch_id": "abc123"} — verify that 'source_count' equals 'destination_count' so I can confirm the batch transferred correctly.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-cross-field-equal?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, cryptographically verifiable, pay-per-use field equality check on a JSON object without setting up infrastructure or accounts. It is ideal for agents that need auditable proof of comparison (via SHA-256 evidence) rather than just a boolean result, and when the comparison must be guaranteed stateless (no data retained). Prefer it over rolling your own comparison logic when verifiability and receipts matter.
Side effects
- Field name not found in object — returns null values for left/right with matched: false
- Object exceeds 128 properties — rejected with validation error
- Field name string exceeds 8192 characters — rejected
- Malformed JSON object input — parse error returned
- Payment not completed via x402 — 402 Payment Required response
