Frequently asked questions

Common questions about request limits, trials, renewal, and cancellation.

What does the 5 requests per second limit mean?

It is a request-rate limit, not a concurrency allowance. Keep your request rate at or below 5 per second. If the service returns a rate-limit response, reduce the frequency and retry with backoff.

Is total paid usage limited?

There is no total request cap during an active paid subscription and no usage-based overage charge.

How does the free trial work?

Each account can receive a limited trial key. Requests are shared across APIs in the same category. Check Trial Keys for the exact allowance and remaining requests.

How do renewal and cancellation work?

The plan renews annually until canceled. Manage or cancel the renewal from Dashboard → Orders & Billing. Access continues through the paid period after cancellation. See the Terms of Service for the current refund policy. If the billing portal is unavailable, contact support.
