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 an array of top-level key names found in the input JSON text, the count of those keys, and a schema identifier string (e.g. 'delx/json-keys/v1').
Example use cases
Inspect unknown API response structure
“I got this JSON back from an API and I have no idea what fields are in it — can you extract all the top-level keys so I know what I'm working with? Here's the payload: {"user_id":"abc123","created_at":"2024-01-01","roles":["admin"],"verified":true}”
Validate expected JSON schema keys
“I need to check what keys are present in this JSON before processing it downstream — can you list all the top-level field names and how many there are? The JSON is: {"order_id":"X99","amount":42.5,"currency":"USD","items":[]}”
Summarize dynamic config file keys
“I have a config JSON from a user submission and I just need to know what top-level properties it defines — can you enumerate the keys? Here it is: {"theme":"dark","locale":"en-US","notifications":true,"max_retries":3}”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-keys?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, no-signup solution for extracting top-level key names from a JSON string — especially in agent workflows where USDC micropayment via x402 is already integrated and you want verifiable, per-call billing without subscription overhead.
Side effects
- Invalid or malformed JSON input causes a parse error response
- Empty string input returns zero keys or an error
- Deeply nested JSON returns only top-level keys, not nested keys — users expecting full recursive key extraction may be surprised
- Payment failure or insufficient USDC balance results in HTTP 402 rejection before processing
