CoinStats API

⭐ Beginner's Pick Cryptocurrency / No Auth Required Beginner HTTPS
Free to Use Varies (check documentation)

Overview

CoinStats is a no-authentication REST API that provides real-time prices, percentage changes, and basic market metrics for thousands of cryptocurrencies. It returns a paginated list of coins sorted by market cap, making it straightforward to build a crypto ticker or price widget without setting up API keys. The free public tier is rate-limited but generous enough for personal projects and prototypes.

Beginner Tip

No sign-up is needed — just call the endpoint directly and the JSON response arrives immediately. Keep your polling interval at 60 seconds or longer to stay within the public rate limit and avoid temporary blocks.

Common Errors & Troubleshooting

429 Too Many Requests Polling the API too frequently from the same IP address
Cache the response locally and refresh no more than once per minute; avoid calling the API in a tight loop.
Empty coins array Requesting a page number that exceeds the total number of pages
Check the pageCount field in the response and stop paginating when your current page equals that value.
CORS error in browser Some endpoints do not include permissive CORS headers
Route requests through your own backend server instead of calling the API directly from browser-side JavaScript.
