Frequently asked questions

Does the link extractor crawl an entire website?

No. It extracts link strings from the single webpage URL you provide. Submit additional pages separately if you need a larger link inventory.

Are duplicate links removed from the result?

No. Source order and duplicates are preserved. Deduplicate the returned strings in your application only if that matches your use case.

Does the API check whether each returned link works?

No. Returned strings are not visited or verified for availability. A separate HTTP-checking step is needed if you want to identify redirects or broken destinations.

What does an empty result mean?

An empty result list can be a successful extraction with no returned links. Check the response status and count rather than treating every empty array as a service failure.

What should I do when link extraction fails?

Handle the documented error response instead of substituting guessed links. The contract uses HTTP 503 with business code 500 for extraction failure, which is different from a successful empty list.

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.
