Implementation notes

When to use CoinGecko

CoinGecko is the most complete free crypto market data API. It covers 10,000+ coins and 800+ exchanges, returns OHLCV data, dominance metrics, exchange volume, and developer/social stats. The Demo plan (no key required for basic endpoints) is sufficient for dashboards and portfolio trackers.

Common pitfalls

CoinGecko distinguishes sharply between the 'Demo' plan (no key) and the 'Public API'. The no-key endpoint at `api.coingecko.com/api/v3/` returns data at 10-30 calls/minute with occasional throttling. The Demo plan (register for a free key, pass it as `x_cg_demo_api_key`) gives a stable 30 calls/minute limit.
The `/coins/{id}/market_chart` endpoint can return very large responses for long date ranges. Requesting 365 days of hourly data for a single coin returns approximately 400KB of JSON. Use `interval=daily` when granularity does not matter.
CoinGecko uses its own coin IDs (e.g., `bitcoin`, `ethereum`, `shiba-inu`) which do not match ticker symbols or CoinMarketCap IDs. Always call `/coins/list` once to build a local mapping from ticker symbol to CoinGecko ID rather than guessing.
Historical price data older than 365 days switches from hourly to daily granularity automatically, with no parameter to override this. If your analysis requires consistent hourly resolution, you must stitch together multiple 1-year requests.

Quick start (bash)

curl "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin,ethereum&vs_currencies=usd,eur&include_24hr_change=true"

From our monitoring

CoinGecko's free tier has had throttling events during crypto market volatility spikes — periods of high trading activity drive significantly more API traffic and we have observed increased 429 responses. Plan for retry logic with exponential backoff.
