CoinMarketCap ID Map

Returns a mapping of all cryptocurrencies to unique CoinMarketCap `id`s. Per our Best Practices we recommend utilizing CMC ID instead of cryptocurrency symbols to securely identify cryptocurrencies with our other endpoints and in your own application logic. Each cryptocurrency returned includes typical identifiers such as `name`, `symbol`, and `token_address` for flexible mapping to `id`. By default this endpoint returns cryptocurrencies that have actively tracked markets on supported exchanges. You may receive a map of all inactive cryptocurrencies by passing `listing_status=inactive`. You may also receive a map of registered cryptocurrency projects that are listed but do not yet meet methodology requirements to have tracked markets via `listing_status=untracked`. Please review our methodology documentation for additional details on listing states. Cryptocurrencies returned include `first_historical_data` and `last_historical_data` timestamps to conveniently reference historical date ranges available to query with historical time-series data endpoints. You may also use the `aux` parameter to only include properties you require to slim down the payload if calling this endpoint frequently. This endpoint is available on the following API plans: - Basic - Hobbyist - Startup - Standard - Professional - Enterprise Cache / Update frequency: Mapping data is updated only as needed, every 30 seconds. Plan credit use: 1 API call credit per request no matter query size. CMC equivalent pages: No equivalent, this data is only available via API.
