About Mock API Response Generator

Produces the shape of response a front end expects while the real endpoint is being built: a bare array, { data: [...] }, a paginated envelope with meta and links, or JSON:API style.

It can also produce error bodies in RFC 9457 problem-details format for 400, 401, 404, 422, 429 and 500, so error handling can be tested before the API exists.

How to use it

  1. 1Type or paste your text, or open a file.
  2. 2Choose any options - the result updates as you type.
  3. 3Copy the result or download it as a file.
