How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns a validation result indicating whether the provided JSON is valid, along with any parsing errors or structural issues found in the input properties.
Example use cases
Validate API response before processing
“I just got a response from another API and I want to make sure it's valid JSON before I try to use it — can you check this for me: {"status":"ok","data":{"id":42,"value":null}}?”
Debug malformed JSON payload
“My app is crashing when it tries to parse this JSON — can you validate it and tell me exactly what's wrong with it: {"user":"bob","scores":[1,2,3,}?”
Pre-submission JSON format check
“Before I submit this configuration object to the server, can you verify it's properly formatted JSON: {"timeout":30,"retries":3,"endpoint":"https://example.com"}?”
Technical details
Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/json-validateWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call JSON validation check without committing to a subscription service. It is appropriate for ad-hoc validation tasks in automated pipelines where you only pay for what you use, settled in USDC on Base. It is well-suited for agents that need to verify JSON integrity before passing data downstream.
Side effects
- Missing or empty input returns an error indicating no JSON to validate
- Malformed input that cannot be parsed returns a detailed syntax error
- Network or server errors on the Render.com host may return 5xx responses
- Payment failure via x402 may result in a 402 Payment Required response before content is served
