Starter Plan
The Starter plan is perfect for those who want to build Bitcoin pricing into their app without a financial commitment. You can make up to 10 requests per minute on this plan and access live pricing and fees. You also have access to the websocket server (see below).
Pro Plan
The Pro plan is intended for those who have an established application with a growing user base. You can make up to 250 requests per minute on this plan, access live pricing and fee data and historical pricing and fee data (coming soon). Websocket connections are also supported (see below).
Live Prices
To provide live pricing we aggregate pubic data from a number of crypto exchanges. The more trades an exchange does, the greater influence it has on the price. By using data from multiple exchanges it means a more accurate price and also offers redundancy if any one exchange stops working.
Live Fees
Get live Bitcoin transaction fees via the API. The fees are provided by Mempool.
Price History pro plan only
The maximum number of historical prices you can retrieve is 25 and the default number of prices returned is 10. You can include a limit parameter in the query string if you would need a specific number of prices returned.
Fee History (coming soon) pro plan only
You will be able to view historical transaction fees via the Sintra API. We record fees on the hour, every hour and once we have enough data we will make this feature available to Pro users.
Websocket Server
Our websocket server allows you to receive prices and fees over a websocket connection. Updates are sent every 10 seconds for unauthenticated connections and 1 second for authenticated connections.
