Free Crypto & Web3 APIs — FAQ
Are there free Crypto & Web3 APIs with no API key?
Yes — 23 of the 37 free crypto & web3 APIs we list need no API key or signup (Kraken is a good starting point). Use the "No key" filter above to see them; they're the fastest to prototype with.
Which free Crypto & Web3 API is the most reliable?
Of the 37 crypto & web3 APIs on our probe schedule, Kraken 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 Crypto & Web3 APIs from the browser?
22 of these crypto & web3 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 Crypto & Web3 APIs OK for commercial use?
1 of the 37 crypto & web3 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 Crypto & Web3 APIs checked?
30 of the 37 crypto & web3 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.
