What is CoinGecko?
CoinGecko is a crypto price and market data aggregator founded on April 8, 2014. Its API has a free Demo plan with 10,000 calls per month at 100 calls per minute; paid plans start at $35 per month (Basic, 100k call credits). It also tracks exchanges, NFTs and onchain DEX data.
How CoinGecko works
CoinGecko builds a coin's price from exchange tickers.
It first drops anomalous tickers: with fewer than three tickers, a price that moves more than 100x from the previous price counts as an outlier, and with three or more, prices outside bounds set by median absolute deviation are excluded. The remaining tickers are combined into a volume-weighted average price. Trust Score grades trading pairs Green, Yellow or Red using liquidity measures such as spread and 2% order book depth, and rates spot exchanges from 1 to 10.
The exchange Trust Score was rebuilt in the Basilisk update of May 2026, which replaced web traffic with direct volume and order book depth checks and added a Regulation Score. The API serves the same data. Demo keys call api.coingecko.com with the x_cg_demo_api_key header, paid keys call pro-api.coingecko.com with x_cg_pro_api_key, and mixing them returns error 10010 or 10011. A keyless public API is rate limited per IP address.
How to start with CoinGecko
- Create a free account, open the Developer Dashboard and click Add New Key to get a Demo key; no credit card is needed.
- The Demo plan allows 100 calls a minute and 10,000 calls a month and requires attribution.
- Every request counts toward the per-minute limit, including 4xx and 5xx errors.
- If you pull data into Google Sheets, CoinGecko warns that shared Google IP addresses can trigger rate-limit errors unless you use a paid key.
CoinGecko fees and limits
- Monthly prices: Basic $35 (100k credits, 300 calls a minute, 2 years of history), Analyst $129 (500k credits), Lite $499 (2M credits) and Pro $999 (5M credits); Enterprise is quoted.
- Yearly billing brings these to $29, $103, $399 and $799.20 a month.
Cards are the default payment method, and crypto is accepted on annual Analyst plans and above. Commercial use on paid plans requires showing Data provided by CoinGecko with a link to its API page.
Risks to know before using CoinGecko
- Paid subscriptions are non-refundable in whole or in part, so test on the Demo tier first.
- Redistributing CoinGecko data commercially needs the Enterprise license.
- Prices are aggregates: outlier filtering can exclude a ticker from the exchange you use, so the CoinGecko figure can differ from your fill price.
- Rate limits count failed requests too, which can keep a naive retry loop locked out.
