Frequently asked questions

What does the URL-to-HTML API create?

It captures a public webpage as a downloadable static HTML document. Use the result for later parsing, content review, indexing, or other workflows that need an HTML file.

Does the API return HTML inline or a file URL?

The documented Data value is an HTTPS URL for the generated static HTML file. Download the file before passing its contents into a parser or storing it in your own archive.

Does one request create a complete offline copy of a website?

No. The input is one webpage URL. The documented response does not promise a recursive website mirror with every linked page and asset bundled for offline use.

Will interactive features continue to work in the saved file?

Do not assume so. The result is static HTML, and interactive behavior may depend on external scripts, APIs, authentication, or resources that are not part of the downloaded document.

Can I provide a raw HTML string instead of a URL?

This endpoint takes a complete public HTTP or HTTPS webpage URL. It does not document a raw-HTML input field, so choose a different operation when you already have the HTML.

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.
