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 a 'result' field with 'found' (boolean) and 'value' (the extracted value or null), a 'status' field ('pass' or 'fail'), an 'operation' identifier, and an 'evidence' block that includes the SHA-256 hash of the input, a flag confirming no data was retained, and a count of external calls made (always 0).
Example use cases
Extract config value from API response
“I just got back this big JSON config blob from our server. Can you pull out the value at '/database/primary/host' for me?”
Check nested order total in e-commerce payload
“Here's a JSON order payload — can you get the value at '/payment/summary/total' so I know what the customer was charged?”
Verify field existence in structured data
“Given this JSON document, check if the path '/user/preferences/notifications/email' exists and what value it holds.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-pointer-get?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, auditable, pay-per-use JSON Pointer resolution without standing up infrastructure. Ideal for AI agents that need to extract values from arbitrary JSON payloads on the fly with cryptographic proof of non-retention. Prefer it over writing inline code when the audit trail or cost predictability ($0.001 USDC flat) matters, or when operating in a trust-minimized environment that benefits from the x402 payment protocol.
Side effects
- Invalid JSON Pointer syntax returns an error or found:false
- Document exceeds 128 top-level properties and is rejected
- Pointer references a non-existent path — returns found:false with null value
- Malformed JSON document causes a parse error
- Request body missing required 'pointer' or 'document' fields
