Frequently asked questions

Why do URLs in JSON contain \/ (backslash slash)?

JSON allows the forward slash to be written as \/. It means exactly the same as / — it is only a text-encoding detail used so strings are safe to embed in HTML. The URL is not broken; a JSON parser decodes it back automatically. Click Clean URLs to strip the backslashes for copying.

How do I extract all URLs from an API response?

Paste the full response into the JSON tab and click Extract URLs. Every http and https URL is pulled out, unescaped and listed. You can then remove duplicates, filter by type or domain, and export to TXT or CSV.

Does it work with Insomnia and Postman?

Yes. Paste an Insomnia response, a Postman export, or any REST or GraphQL payload and extract URLs instantly. The tool reads raw text, so the exact export format does not matter.

Is my data uploaded to a server?

No. All cleaning, extraction, validation and preview happens locally in your browser with JavaScript. Nothing you paste is transmitted to or stored on any server.

Can I preview images and videos from the URLs?

Yes. Image URLs (jpg, png, webp, gif, svg, avif and more) and video URLs (mp4, webm, mov) are rendered in a media preview grid so you can verify assets without opening each link.

Can I export the extracted URLs?

Yes. Use Copy to copy the visible list to your clipboard, or Download TXT and Download CSV to save the results — ready for SEO crawls, link checkers or migration scripts.

How do I clean a list of plain URLs?

Switch to the URL List tab, paste one URL per line, and use the same dedupe, filter and export tools. It is ideal for preparing URL lists for SEO audits.

Is API URL Kit free?

Yes. It is completely free, requires no signup or account, and runs entirely in your browser.
