What resources can I explore?

All six JSONPlaceholder resources: /posts (100 items), /comments (500 items), /albums (100 items), /photos (5000 items), /todos (200 items), and /users (10 items).

Can I fetch a single record by ID?

Yes. Enter an ID in the filter box to fetch a single resource (e.g. /posts/1). You can also filter related resources, for example all comments for post 1 (/posts/1/comments).

How do I use the generated fetch() snippet?

Click 'Copy fetch()' and paste the snippet into your browser console, Node.js, or any JavaScript project. It includes the full URL and logs the response JSON.

Does this make real API calls?

Yes. The requests go directly to https://jsonplaceholder.typicode.com from your browser, so you see real live responses. No server proxy is involved.

このツールについて

JSONPlaceholder is a popular free REST API used for testing and prototyping. This explorer lets you browse all six resources — posts, comments, albums, photos, todos, and users — without writing a single line of code. Filter by ID or parent resource, view the raw JSON response with syntax highlighting, see the exact API URL being called, and copy a ready-to-run fetch() snippet to your clipboard. Perfect for learning REST API concepts, demoing front-end code, or quickly grabbing sample data structures.

3 Click 'Fetch' to make the API request and view the JSON response.
4 Review the API URL shown above the response to understand the endpoint structure.
