Support FreeAPI.watch
FreeAPI.watch checks 133 free APIs and MCP servers every hour and publishes what it measures. No paywall, no account, no rankings for sale. It is maintained by one developer in his spare time.
The hosting genuinely costs nothing — the whole thing runs on Cloudflare's free tier — so this is not a rescue fund. Support here buys time: hours spent verifying new APIs, writing the integration notes, and chasing down why something broke.

Free ways that help just as much
Money is the least useful thing you can give a project like this. These matter more:
- Tell us when we're wrong. A free tier that quietly changed, an API we list as alive that isn't, a rate limit that's different in practice — corrections are the single highest-value contribution. Email us or open a thread in the community.
- Suggest an API we should be watching. Every candidate gets tested before it enters the catalog.
- Link to us when an API dies and you write about the replacement. Measured uptime data is more citable than another list of links.
- Subscribe to the weekly digest — what died, what got added, what changed. One email, Fridays.
Running a company instead?
If your product serves developers, sponsorship reaches this audience at the moment they are choosing what to build on — and it funds the monitoring far more meaningfully than coffee does. Rankings are never part of the deal.
However you use the site: it stays free, and the data stays measured. That is the whole point.
