What APIHub does

One place to find, test, and build with real APIs -- not just a static list.

Explore & search

Keyword or semantic search across the whole catalog, with real filters for auth type, HTTPS, CORS, and category.

Playground

Send a real request to any Playground-enabled API right in the browser -- no signup, no separate tool.

Build My App

Describe an app idea in plain English and get matched real APIs, with starter code wired to them.

Live health monitoring

Every API is checked on a real schedule -- uptime, latency, and outages are tracked automatically, not hand-verified once.

Auto-enriched descriptions

Thin, one-word upstream descriptions get replaced with a real summary, grounded in that API's own documentation.

Submit an API

Know an API that isn't listed yet? Add it and it goes through the same scraping and health checks as everything else.

How it works

Search or describe your idea

Look up an API by name or category, or just describe the app you want to build in plain English.

See real, verified matches

Every result shows real auth/HTTPS/CORS info and a live Playground badge -- not guesses.

Test it, then build with it

Send a real request in the Playground, or let Build My App wire up starter code against it.

What is APIHub?

APIHub is a continuously-maintained directory of public APIs -- not a static list someone curated once and forgot about. Entries are scraped for real documentation, health-checked on a schedule so listings reflect whether an API is actually up right now, and had thin or missing descriptions replaced with a real summary grounded in each API's own docs. On top of the catalog, Build My App matches a plain-English app idea to real APIs and generates starter code, and the Playground lets you send a live request to any supported API before writing a single line of your own.
