## Coinlayer API

**[Coinlayer](https://coinlayer.com/?utm_source=Devto&utm_medium=Leads%20Acquisition&utm_content=WhichCryptoExchangeAPIisBetter&utm_campaign=WhichCryptoExchangeAPIisBetter)** is a powerful one-stop API focused on delivering accurate coin exchange rate data gathered from over 25 most significant cryptocurrency exchanges around the globe.

## CoinMarketCap API

- **Limited customer support.**

CoinMarketCap’s customer support is available only to the Enterprise subscription users, and even for them, it is limited to email.
