Frequently asked questions

What does the article image extractor return?

It returns an ordered, deduplicated list of image candidates from a public article URL. Each item can include src, absoluteUrl, alt, width, and height.

Does the API download the images for me?

No. The response contains image references and metadata. Download the images separately if your workflow needs local files, and check the source permissions before storing or republishing them.

Can it recognize products or read text inside an image?

No. This endpoint extracts image candidates from a webpage; it does not inspect image pixels, perform OCR, or return product attributes inferred from an image.

Are image dimensions and alternative text always available?

No. Width and height are reported from the HTML when available, and alt can be empty. These fields should not be treated as verified dimensions of every downloaded image.

Can I submit an image file instead of an article URL?

This endpoint accepts a public HTTP or HTTPS article URL, up to 2,048 characters. It does not accept an image upload or a standalone image-recognition request.

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.
