The Indexes API is a product designed for devs, investors, and traders that provides access to crypto index data. You can obtain insights from +7700 crypto indices and +2200 assets through REST and WebSocket protocols.

The product offers ultra-fast updates, real-time and historical data, and security standards compliance.

API calls are counted when you make a request to the API. Each request consumes 1 API call.

For example, if you request to get the VWAP index, it will consume 1 API call.

Messages sent to us via WebSocket are also counted as API calls.

Choosing the right Indexes API plan depends on your specific needs, usage patterns, and business objectives. Here’s a guide to help you decide between a Pay-As-You-Go plan, a Business plan, and an Enterprise plan:
