Plan comparison

What “Last N” means

On the Starter plan, market history access is limited to the most recent BTC markets of each type:

• BTC 5m & 15m: Access the 50 most recent markets
• BTC 1h & 4h: Access the 24 most recent markets
• BTC 24h: Access the 5 most recent markets

ETH, SOL, Binance Spot, and Binance Futures are not available on the Starter plan. Pro and Suite plans include access to 31 days of historical market data across BTC, ETH, and SOL. Binance Spot and Binance Futures endpoints are available on Pro and Suite plans only. Historical Binance depth snapshots are currently available for BTC/USDT.

​

Snapshot access

All snapshots per market are available on every plan, including Starter. There are no snapshot limits — if you can access a market, you get all of its snapshots.
