The Coinranking API uses API keys to authenticate requests.

Authentication to the API is performed via a custom HTTP header. Provide your API key as the value of the X-Access-Token, like x-access-token: coinranking53a...9e4. Create a free account to get an API key.

All API requests must be made over HTTPS. Calls made over plain HTTP will redirect to HTTPS.


curl https://api.coinranking.com/v2/coins \
  -H x-access-token: 53a0b0a7e4f2fa59519e4

Why would I authenticate?

You can only do a very limited amount of requests without authenticating. Read on to learn more about our rate-limits, or check out our pricing page.

Rate limits

The amount of requests you can do before you run into our rate limit depends on your API key. With our free API key you can make about 10K requests per month. If you need more you can upgrade to the Hobbyist or Pro plan, which you can read more about at our pricing page. Without a key you can still make a very limited amount of requests so you can quickly test if our endpoints fit your needs, or debug a little bit during development. The unauthenticated requests are not guaranteed to work, so we advice you to get a key to not unexpectedly run into the rate limiter.

Types of rate limiting

We have rate limits for several time intervals. We protect against burst requests by limiting the free keys to about five requests per second. Our free key is limited to 10K requests per month. Unauthenticated requests are limited much more per month, and have limits per minute and hour as well. The current unauthenticated rate limits might change in the future to whatever we see fit; for guaranteed rate limits get one of our free keys.

Rate limit response headers

Every request you do returns information about the rate-limit, so your application can adapt before reaching the limit.


The maximum amount of requests in a second


The maximum amount of requests in a minute


The maximum amount of requests in an hour


The maximum amount of requests in a month


The amount of requests you can still do in a second


The amount of requests you can still do in a minute


The amount of requests you can still do in a hour


The amount of requests you can still do in an hour


This is the rate-limit that is the first to run out. E.g. when you can still do 10000 requests this month, but only 5 this minute, it will show 5


This will tell you the amount of seconds remain until the quota of your lowest rate-limit will be restored to its maximum


The amount of requests remaining for the lowest remaining limit


You can generate a key for free. The free tier will remain free, but it has some limitations such as a more restrained rate limit and it lacks some endpoints. So if you need more than the free tier provide, have a look into our plans on our pricing page.


If you are developing an application that directly makes requests from the browser to our API, you will run into issues with Cross Origin Resource Sharing (CORS). To prevent this, our API will respond with your custom domain in a CORS header. You can set your custom domain on the settings page. CORS is supported in our Hobbyist plan and above.


Icon URLs are provided as .svg, for example the logo for Bitcoin is:


We also support .png on all our coin and exchange logos. If you prefer this, just replace the svg extension with png:



We’re constantly trying to improve our API, to provide you with the best possible experience. That is why we would like to hear what you think of it. Help us by answering two short questions.

Older API versions

API v1 is still online, and will remain so for the foreseeable future. The use of API v1 is deprecated, so we strongly advise you to use API v2. You can still read the documentation for API v1.
