All of our API endpoints are metered in Compute Units (CU).
Each one of our subscription plans comes with a certain amount of CUs included. If you exceed your CUs for a given month, overages will apply. You have the option to disable this for your account, which means that once you exceed your allocated CUs, the API key will be disabled until the next billing cycle.
Note that some endpoints have a fixed cost per API call, and some have a variable cost that depends on how many items are returned (this most typically applies to the txs
endpoints, where the total amount of CUs billed will depend on how many transactions are returned).
For example, if you call txs
on EVM with a pageSize
of 50 and you retrieve 50 transactions on that call, your CU cost will be:
25 * 50 = 1250 CUs
If you make that same call passing a pageSize
of 50 but there aren't 50 items to return, you'll only be billed for the transactions actually returned. So if you only get 10 transactions back, your CU cost will be 250.
