Free Developer Tools APIs — FAQ
Are there free Developer Tools APIs with no API key?
Yes — 103 of the 183 free developer tools APIs we list need no API key or signup (ListLoco API is a good starting point). Use the "No key" filter above to see them; they're the fastest to prototype with.
Which free Developer Tools API is the most reliable?
Of the 183 developer tools APIs on our probe schedule, ListLoco API leads on measured uptime (100% over 90 days). Reliability here is verified from our own scheduled checks, not the provider's claims — sort by "Reliable" to rank the rest.
Can I call these Developer Tools APIs from the browser?
110 of these developer tools APIs send CORS headers over HTTPS, so you can fetch them straight from front-end code — no backend proxy. Filter by "Browser OK" to see them; the rest need a server-side call.
Are these free Developer Tools APIs OK for commercial use?
1 of the 183 developer tools APIs allow commercial use on the free tier; the rest are unclear or personal-only. We record service terms and the data license as separate fields on every listing — check both before you ship.
How often are these Developer Tools APIs checked?
141 of the 183 developer tools APIs are on our probe schedule and re-tested every sweep. We log uptime, latency and response-shape changes on each, and move any that stay down to the graveyard so you can see what died and when.
