About API URL Kit
A free, no-signup developer utility.
API URL Kit is a browser-based tool that helps developers pull clean, usable URLs out of JSON payloads, API responses, Postman exports, Insomnia responses and GraphQL results — without copy-pasting into a code editor or writing a throwaway script.
What it does
- Unescapes JSON-escaped URLs (turns
\/back into/). - Extracts every URL from a response and removes duplicates.
- Validates URLs and previews image and video links.
- Filters by type or domain and exports clean lists to TXT or CSV.
Why we built it
Anyone working with APIs hits the same friction: a response is full of escaped or nested URLs, and getting a clean list out of it is annoying. API URL Kit does that in one click, entirely in your browser — nothing is uploaded to a server.
