Frequently Asked Questions
What data does the Crypto APIs Market Data API return for a cryptocurrency?
It returns current asset details including live price, circulating and max supply, market capitalization, 24-hour trading volume, and token contract addresses across protocols. You can look up an asset by its symbol (e.g. BTC) or by its unique asset ID. Data is sourced from CoinMarketCap.
Does the Market Data API provide OHLCV candlesticks or order-book data?
No. The Market Data API provides current price and current asset-to-asset exchange rates only. It does not include OHLCV/candlestick history or per-exchange order-book data.
How do I get the exchange rate between two assets, like BTC to USD?
Use the exchange-rate endpoints, which return the current rate between any two assets. You can request the rate either by asset symbols (for example BTC to USD) or by the two assets' unique asset IDs.
How many assets does the Crypto APIs Market Data API cover?
The API covers approximately 14,600 crypto and fiat assets, sourced from CoinMarketCap. You can enumerate the full supported list via the list-supported-assets endpoint, which supports pagination and a filter for crypto or fiat asset types.
Can I look up assets by symbol or do I need an asset ID?
Both are supported. Asset details and exchange rates can be requested either by human-readable symbol (such as BTC or ETH) or by the asset's unique asset ID. Symbol-based lookups are convenient, while asset IDs disambiguate tokens that share a ticker.
