Try it out - Mint Starter Kit

This page showcases Mintlify’s interactive API playground wired to JSONPlaceholder. No authentication is required. You can modify inputs and send real requests live.

Live requests (from OpenAPI)

The blocks below use the base URL https://jsonplaceholder.typicode.com from the OpenAPI spec.

- name: List posts (limit 3)
  method: GET
  path: /posts
  query:
    _limit: 3
  headers:
    Accept: application/json

- name: Get a post by id
  method: GET
  path: /posts/1
  headers:
    Accept: application/json

- name: Create a post
  method: POST
  path: /posts
  headers:
    Content-Type: application/json
  body:
    json:
      userId: 1
      title: "Using Mintlify Try it out"
      body: "Created from the live playground."

- name: List comments for a post
  method: GET
  path: /comments
  query:
    postId: 1
