JSONPlaceholder

aid: jsonplaceholder
name: JSONPlaceholder
description: >-
  JSONPlaceholder is a free, no-auth fake REST API for prototyping, tutorials, and testing. It exposes six relational
  resources — posts, comments, albums, photos, todos, and users — over six standard REST routes per resource. All write
  operations (POST, PUT, PATCH, DELETE) are accepted and respond as if successful, but no changes are persisted. The
  service is built on the open-source json-server engine (also by typicode) and serves billions of requests per month
  with no rate limits or authentication.

  - name: JSONPlaceholder REST API
    description: >-
      Free fake REST API surface exposing six relational resources (posts, comments, albums, photos, todos, users).
      Supports GET / POST / PUT / PATCH / DELETE plus nested routes (e.g. /posts/1/comments) and basic query-string
      filtering (e.g. /comments?postId=1). Write operations are simulated — the service responds with the expected
      payload but does not persist changes.
