DummyJSON

Purpose: DummyJSON provides fake REST API data for frontend development, building, and testing without backend setup.
Datasets: The site lists products, carts, users, posts, comments, quotes, todos, recipes, images, and authentication resources.
Usage: The documentation says DummyJSON can be used with any type of frontend project needing dummy data in JSON format.
Pagination: Resources support limit, skip, and select query parameters, and limit=0 returns all items.
Response delay: A delay query parameter can simulate responses from 0 to 5000 milliseconds.
Custom API: Users can create a hosted mock REST API endpoint with their own JSON response body and select GET, POST, PUT, PATCH, or DELETE.
Custom API limits: Custom response endpoints last 90 days and accept JSON response bodies up to 300 KB.
Webhook tool: The webhook inspector captures incoming requests for debugging, supports all HTTP methods, and keeps endpoints live for 24 hours.
Webhook limits: Each webhook stores up to 100 requests, accepts payloads up to 300 KB, and strips authorization, cookie, and x-api-key headers before storage.
TOTP tool: The TOTP tool generates real-time verification codes and supports base32 secrets and otpauth URIs.
Authentication: The auth endpoints demonstrate login, access and refresh tokens, and authenticated resource access.
Mock data behavior: Adding or updating products simulates the request and returns a result without changing the server’s stored data.
Scale: The homepage states that DummyJSON serves over 500 million requests monthly.
