Limits

The limits that keep every capture fast and fair. Most of them are generous enough that you will never meet them.

Captures at the same timeLink to this section

Every account can run up to 3 captures at the same time, unless its limit was raised. A request that would go past that answers with 429 and a message that names your limit. As soon as one of your captures finishes, the next one can start.
