CoinGecko is one of the best platforms for tracking investments and assets. The site is very well organized, allowing me to easily manage all my holdings and discover new ones. I use it frequently throughout the day and really value its simple yet feature-rich interface. It lets me scan the market and take advantage of all the available tools, such as linear and candlestick charts. Even the free version is excellent and feels complete in every respect.

• The coverage is really comprehensive, with unified REST endpoints for live and historical prices, market data, metadata, exchanges, derivatives, NFTs, categories, and global metrics, which keeps integration surface area small while still enabling depth when needed. • The /onchain suite exposes DEX pools, token-by-contract, and OHLCV so it is possible to build candlestick charts and surface liquidity insights alongside centralized market data, and this is explicitly powered by the same stack as GeckoTerminal, which helps with consistency of on‑chain semantics. • Real-time and historical retrieval is straightforward via simple/price, coins/markets, and coins/{id}/market_chart, so it takes minimal effort to fetch spot quotes and time series for charting or backtests without stitching multiple vendors. • Plan structure and docs are clear: paid tiers lift rate limits materially, list exclusive endpoints, publish SLA expectations, and document key placement in header or query for the Pro domain, which makes production hardening predictable. • The platform breadth is strong: 17k+ tracked coins across 1k+ exchanges, multi-chain token coverage, and NFT collection data, so a single API can underpin portfolio, screening, and discovery use cases without multiple data contracts. • Reliability and support positioning are enterprise-friendly, with in-market operation since 2014, a stated 99.9% uptime SLA on enterprise, and round-the-clock operations, which signals a focus on stability at scale. • Higher paid-tier rate ceilings reach the hundreds to thousands of calls per minute per key, which aligns with real application polling patterns and reduces the need for aggressive client-side throttling.

The CoinGecko API offers an extensive range of market data, including real-time prices, historical charts, and detailed coin metadata, all without requiring an expensive enterprise plan. The documentation is clear, the response times are fast, and the rate limits are generous enough even on the free tier. Their Pro API adds great value and is priced reasonably for scaling projects. We also appreciate the granularity of data across multiple timeframes and the consistent uptime.
