Overview

CoinRanking offers a REST API that delivers live price, market cap, and ranking data for thousands of cryptocurrencies. Each coin is assigned a unique UUID you can use to fetch detailed stats, historical price charts, or filter coins by category. The API uses a tiered key system where a free-tier key grants enough quota for learning projects and small dashboards.

Beginner Tip

Sign up at coinranking.com to get a free API key, then pass it as an x-access-token header. Start with the /coins endpoint — it returns a ranked list of coins with prices and requires no parameters beyond your key.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://developers.coinranking.com/api/documentation";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-09-21. Knowing the shape of an error before you hit it makes error handling much easier to write.

HTTP 404 Requesting a path that does not exist application/json
{
  "status": "error",
  "code": "NOT_FOUND",
  "message": "API Not found."
}
HTTP 422 Sending an invalid value for "limit" application/json
{
  "status": "fail",
  "type": "VALIDATION_ERROR",
  "message": "limit must be at least 1 and most 5000"
}

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized Missing or incorrect API key in the request header
✓ Add the header x-access-token: YOUR_API_KEY to every request; do not put the key in the URL query string.
429 Too Many Requests Exceeding the free-tier rate limit (10 requests/second)
✓ Add a short delay between requests in loops, or cache responses locally to reduce repeat calls.
Coin UUID not found Using a coin symbol (e.g. BTC) instead of the API internal UUID
✓ First call /coins to retrieve each coin UUID, then use that UUID in detail endpoints like /coin/{uuid}/history.
