Sponsor FreeAPI.watch
FreeAPI.watch monitors 103 free APIs and MCP servers with hourly checks and publishes measured uptime, honest free-tier breakdowns, and integration editorial. Our readers are developers at the highest-intent moment there is: actively choosing which API to build on.
If your product serves developers — an API, a devtool, infrastructure — this is your audience, met exactly when they're deciding.
Formats
📬 Newsletter sponsorship — API Watch Weekly
A single clearly-marked sponsor slot in the weekly issue: your headline, two sentences, one link. Sent every Friday to a growing list of API-hunting developers. Exclusive — one sponsor per issue.
📊 Category sponsorship
The "Sponsored alternative" block on a category page (weather, finance, geocoding, news, crypto, dev-tools, MCP) and its API detail pages. Always labeled sponsored, always separate from the measured rankings — we never sell positions in the ranking itself.
🌐 Site sponsorship
A discreet "Supported by" mention site-wide (113+ pages) plus a slot in the newsletter. For tools that want durable presence in front of this audience rather than a one-shot.
☕ Not a company? Buy us a coffee
If FreeAPI.watch saved you from building on a dead API, you can support the hourly monitoring for the price of a coffee — no account needed, one-off, takes 30 seconds.
What we don't sell
- Rankings. Positions in our lists come from measured uptime, speed, and free-tier quality. No exceptions, no premium placement inside the data.
- Unlabeled placements. Everything sponsored says so, with
rel="sponsored"in the markup. - Subscriber data. Never shared, never rented.
