Get a pointer to real API testing tools — this page does not actually validate or parse your API response.

- 1Paste your API response (optional — it isn't analyzed here)
- 2Click Process
- 3Follow the link to Postman or Insomnia for real validation
Frequently Asked Questions
No — clicking Process shows a fixed message recommending real tools; your pasted response isn't parsed, checked against a schema, or validated by this page.
Postman or Insomnia both support schema validation, test scripts, and response assertions against live or mocked API calls — this tool's own output points you there.
Partially — if you already have the response body and a schema, the JSON Schema Validator can check required fields and basic types. It won't make the actual API call or check status codes/headers the way Postman/Insomnia do.
No — since no real validation happens, nothing is analyzed or sent anywhere.
