Pizza Orders API — free mock REST API for testing

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

The Pizza Orders API is a small order-lifecycle service: a menu, orders that move through states, and an oven endpoint that fails on purpose. It is the page to open when you need a guaranteed, repeatable 500 — most sandboxes make server errors impossible to reproduce, which is exactly why retry logic and error handling so often ship untested.

Base URL: https://funapi.dev/api/pizza/v1 · 9 endpoints · OpenAPI 3.1 spec and Postman collection available. New here? Read the getting started guide.

What you can practise here

• Call the oven endpoint for a reliable 500 and verify your client retries, backs off, or surfaces the error rather than hanging.
• Send a PUT to an endpoint that only accepts POST and read the 405 together with its Allow header.
• Cancel an order twice and use the 409 to check that your code treats conflict as a state problem, not a transport failure.
• Hit the deliberately slow endpoint to confirm your HTTP client timeout is actually configured and actually fires.

menu

six pizzas, one controversial

• DELETE /pizza/v1/menu — Delete the menu — always 405, the menu is read-only
• GET /pizza/v1/menu — Get the menu

orders

received → baking → out-for-delivery → delivered

• POST /pizza/v1/orders — Place an order (validated)
• GET /pizza/v1/orders/{id} — Track an order
• PUT /pizza/v1/orders/{id}/status — Update order status (requires Bearer auth)
• PATCH /pizza/v1/orders/{id} — Partially update an order (address or size)
• DELETE /pizza/v1/orders/{id} — Cancel an order (409 if already delivered)

oven

do not trust the oven

• GET /pizza/v1/oven/status — Always returns 500 — for negative tests
• GET /pizza/v1/oven/preheat — Preheat the oven — always takes ~3s
