> A curated, **community-maintained** collection of **340+ public APIs** across **55 categories** for developers, students, startups, hackathons, and open-source projects.
>
> This repository helps you quickly discover APIs for AI, Jobs, Weather, Finance, Education, Health, Security, Sports, Open Data, Transportation, and many more. Each entry includes the API name, a short description, and its official endpoint to make integration simple and fast.
>
> This is an open-source project — anyone can propose new APIs, flag broken ones, or improve descriptions via pull request. See [Contributing](#contributing) below.

**Last reviewed:** August 2026. Entries marked ⚠️ now require a paid plan / API key that wasn't previously needed, or have reduced free-tier access — they still work but check current pricing before building on them. Dead or fully shut-down APIs from the previous version have been removed and replaced. Every entry in this revision was individually re-checked against its current documentation before inclusion.

## Keeping this list healthy

This repo aims to only ship **entries that currently work**. To keep it that way:

- Every PR that adds an API should include a link to its official docs and a one-line note on the current free-tier terms (key required? rate limit?).
- Entries that start requiring payment or a key where they didn't before should be flagged with ⚠️, not deleted — they still work, just note the change.
- Entries that are fully dead (DNS doesn't resolve, docs page gone, org confirms shutdown) should be struck through and, where a reasonable alternative exists, replaced rather than just removed.
- Consider wiring up a scheduled link-checker (e.g. [lychee](https://github.com/lycheeverse/lychee) or [markdown-link-check](https://github.com/tcort/markdown-link-check)) as a GitHub Action so broken links surface automatically instead of going stale silently.

## Contributing

Contributions are welcome and are what keep this list accurate:

1. **Fork** the repo and create a branch for your change.
2. **Add or update** an entry in the relevant category table, keeping the existing column format (`S.No | API Name | Description | API`).
3. **Verify** the API is currently live and free (or clearly note its access requirements) before submitting.
4. **Open a pull request** describing what changed and why (new API, broken link fix, pricing change, etc).
5. For a brand-new category, also add it to the Table of Contents.

Please keep descriptions to one short line and avoid duplicate entries across categories unless the API is genuinely relevant to both.

## License

This list is released under the [MIT License](https://opensource.org/licenses/MIT) — free to use, share, and adapt with attribution. Note that the license covers this document itself; each individual API listed has its own separate terms of service, which you should review before use.
