How this service works
Generate a realistic mock API response with proper headers, status codes, and schema-matching body data.
Output
Returns a realistic mock HTTP response including properly structured body data matching any provided JSON schema, appropriate headers, and the requested status code — suitable for use in tests, stubs, or development environments.
Example use cases
Example prompt
“Can you generate a realistic mock GET response for https://api.example.com/users/123 with a 200 status code and a response schema that includes id, name, and email fields?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/api-mock-responseWhen to prefer
Use this endpoint when you need a realistic, schema-matching mock API response for a specific URL and HTTP method during development or testing, especially when you want body data that conforms to a given JSON schema. Prefer this over hand-crafting mock data when you need plausible, varied fake responses quickly without setting up a full mock server.
Side effects
- Invalid or missing URL in queryParams returns a 400 error
- Unsupported HTTP method (e.g. POST, PUT) returns a validation error since only GET, HEAD, DELETE are allowed
- Malformed response_schema object may result in a generic or empty body
- Network or service unavailability returns a 5xx error
- Payment not provided or invalid returns a 402 Payment Required
