+The [API requires at least 5 seconds between polls](https://captcha-solver.com/en/docs/how-it-works).
+The SDK defaults to 10 seconds, like the official 2Captcha Python SDK. `solve()`
+waits for `polling_interval` before its first poll and between polls.
 Its default 120-second polling window is independent of the API's five-minute
 task lifetime. A local timeout does not cancel a task or mean that the API
 failed to solve it. Use `create_task()` and keep its `task_id` if you need to
