CoinGecko
The most widely used market data reference in crypto, with coverage far beyond the majors and an API that is free enough to actually build on. Methodology on volume reporting is better than it used to be but still leans on exchange-reported figures.
Best for: Broad market reference data with a usable free API

No custody, no key access. Optional accounts for portfolio tracking only.
Free tier is genuinely usable including API access; paid tiers are clearly priced.
Established company with clear terms and disclosed methodology.
Very broad coverage with reliable pricing. Volume figures still depend partly on exchange self-reporting, which is a known weakness of the whole category.
Approachable for beginners, with good documentation and a well-designed API.
Strengths
- Very broad asset coverage with reliable pricing
- Free API that is realistic to build on
- Approachable for people new to the market
Against it
- Volume data still leans on exchange self-reporting
- Portfolio features are basic
- Rate limits on the free tier bite quickly at scale
The reference layer
CoinGecko covers more assets than anyone with an API free enough to actually build on — 8.8 on access, joint-highest here with TradingView. For pricing and market reference it is dependable and well documented.
Volume figures still lean partly on exchange self-reporting, which is a known weakness of every aggregator rather than a CoinGecko failing. Treat reported volume as an indication, not a measurement.
Frequently asked questions
Is CoinGecko volume data accurate?+
Pricing is reliable. Volume depends partly on exchange self-reporting, which is trivially inflated, and no aggregator has fully solved it. Use volume comparatively rather than as an absolute figure.
Is the CoinGecko API free?+
There is a free tier that is realistic to build on, rate-limited enough that it bites at scale. Paid tiers are clearly priced.
CoinGecko or DefiLlama?+
Different jobs. CoinGecko is market and price reference across a very broad asset list; DefiLlama is protocol metrics with a published methodology and open adapter code. For DeFi specifically, DefiLlama is the better source and it ranks above CoinGecko in our table.
