Unlimited REST

There is no limit to how much you can use our crypto data APIs. No maximum queries per minute or daily call limits on all premium plans.

Low Latency

Our market data platform provides low latency real-time data with a mean latency of 20ms, orders of magnitude faster than competitors.

Snapshot APIs

See the entire market at a glance with our powerful Snapshot APIs. You can also query the gainers and losers for the current day.

Aggregates

1min - 1yr aggregate intervals. We allow you to query our aggregate crypto API in the size you want. 1 min, 7 mins, 16 days, anything is possible.

Transparent Pricing

Get crypto data directly from the source, and know exactly what you're going to pay. Don't waste time and money on sales or middlemen.

Level2 Books

We combine the level2 book from the crypto exchanges into a single, uniform order book. Now you can see a book of the entire market, not just 1 exchange.
