Documentation
Reference docs designed to work with the playground.
Browse every Fake API for Devs domain, inspect real routes, copy language-specific examples, and deep-link teammates into the same selected endpoint.
Quick start
Use the shared base URL
Every route hangs off the canonical Fake API for Devs host, so examples stay copy-pasteable across docs and the playground.
Quick start
Skip auth during prototyping
Routes are public by design, so frontend teams can focus on flows and state instead of access tokens.
Quick start
Test realistic behavior
Dial in pagination and synthetic latency to verify skeleton states, empty states, and longer lists.
Sandbox
Enable your personal sandbox
Generate a free session key and include it as a header. Your POST, PATCH, and DELETE calls persist for 12 hours in an isolated namespace.

A calmer docs experience for technical work.
Check status codes deliberately
Treat the APIs like production services and handle error states cleanly instead of assuming a happy-path 200 every time.
Keep examples executable
Use the generated snippets as your source of truth so routes, headers, and payload shapes stay synchronized.
Deep-link the exact route
Share docs and playground links that already contain the selected method and path when you need aligned debugging.
Sponsor new endpoints
Help fund the next batch of routes
We reinvest support directly into deeper domain coverage, more examples, and clearer docs for the routes teams actually use.
- More sample payloads
- Better niche-domain coverage
