Fun API Playground

18 free, no-signup mock REST APIs (Friends, Star Wars, Harry Potter, Pokémon, Pizza & more) with Swagger-style docs, Bearer auth, pagination, GraphQL, webhooks, and every HTTP status code — 400, 401, 403, 409, 412, 418, 429, 500 — to practice QA and API testing.

This interactive playground needs JavaScript enabled to run the API engine in your browser.

Pizza Orders API Docs — Fun API Playground

A tiny pizzeria backend: menu, order placement with validation, an order-status flow — and /oven/status, which always returns 500 for negative testing.
