URL shortener API
24 September 2026 ยท 4 min read
A URL shortener API creates the same gcut.in link your site would make by hand, from your own app. Try one link first on https://gcut.in/. When the result is what you want to send, wire the same step into code.
What to build against
- Send the full destination URL, including
https://. - Read the short link from the response and store it with your own record.
- A custom short code needs a paid plan. Free calls get a generated code.
- The same guest and account limits apply: 5 links as a guest, 30 on a verified free account, 30 days on the free tier.
Request fields, auth, and examples are on the API page.
When the website is enough
If a person is shortening one link, they do not need the API. The homepage box is the whole flow. Use the API when a form, a bot, or another product should create links without opening gcut.in each time.
