No key does not mean no limits

A keyless API cannot tell its users apart, so it limits by IP address instead. That has three consequences worth knowing before you ship.

You share the limit with your neighbours

On serverless platforms and shared hosting, thousands of projects leave from the same IP ranges. Popular keyless endpoints, crypto prices in particular, answer HTTP 429 to those ranges for much of the day. Calling from the visitor’s browser spreads requests across their IPs, which is one reason the CORS mark matters.

Some operators ask for a name instead of a key

MET Norway, the US National Weather Service, MusicBrainz, Wikipedia and a few others require a User-Agent header that says who you are, ideally with a contact address. Requests with a generic library User-Agent may be refused. The API pages here note it where it applies.

Free is often for non-commercial use

Open-Meteo, for example, is free for non-commercial projects and sold for commercial ones. Others require a visible credit. The verifier can tell you an API answers; only its terms can tell you whether you may use it. Each API page links to the official documentation.

What to do about it

  • Cache every answer for as long as the data stays valid. A daily exchange rate does not need a request per page view.
  • Set a timeout and show a clear message when the API does not answer. Our verifier uses five seconds.
  • Keep a second API for anything your product cannot work without. The category pages make it easy to find one.

Questions

What is a keyless API?

An API that answers a plain HTTP request with no API key, token, OAuth flow or account. You can paste its URL into a browser or curl and get data back.

Are keyless APIs really free?

They cost nothing to call, but they are not unlimited. Operators protect them with rate limits per IP address, and some restrict commercial use. Check the terms linked from each API page.

Why do some APIs here mention a User-Agent?

A few operators, such as MET Norway, the US National Weather Service and MusicBrainz, ask every client to identify itself in the User-Agent header instead of using a key. Browsers send one automatically; in server code you need to set it.

What happens when I exceed a keyless rate limit?

Most APIs answer HTTP 429 until the window resets. On shared hosting and serverless platforms you share an IP range with other customers, so you can hit the limit without having sent many requests yourself. Cache what you can.
