Implementation notes
When to use CoinMarketCap
CoinMarketCap suits projects that need CMC-branded rankings specifically — many institutional and media outlets cite CMC numbers, so using CMC keeps you aligned with the dominant industry reference. Free tier covers basic crypto market data with 10,000 calls/month.
Common pitfalls
- The free 'Basic' plan only exposes a subset of endpoints — primarily latest quotes and the listings endpoint. Historical data, OHLCV, and metadata require paid tiers starting at $79/month.
- Quotes are denominated in USD by default. To convert to other currencies, pass the `convert` parameter; multiple conversions per call (e.g., `USD,EUR,JPY`) are billed as separate calls against your quota.
- Rate limiting uses a 'credit' system rather than simple call counts — some endpoints cost 1 credit, others cost 5+. Plan your call budget based on the credit table in the docs, not just request count.
