# skrat.im

> Free URL shortener from Slovakia (Slovak "skrátim" = "I will shorten"). Two short-link domains, skrat.im and krat.im, each with its own alias namespace. Custom aliases, QR codes, cookie-free click statistics, expiry by date or click count, password protection, link preview (append "+"), bulk shortening, REST API and an MCP server for AI agents. No sign-up needed; accounts are optional and free.

Languages: Slovak (https://skrat.im/), Czech (https://skrat.im/cs/), English (https://skrat.im/en/).

## How to shorten a URL programmatically

- REST: `POST https://skrat.im/api/v1/links` with JSON `{"url": "https://example.com/long"}`. Optional: alias, domain (skrat.im | krat.im), title, expires_in_days, max_clicks, password, public_stats, utm_*.
- Plain text: `GET https://skrat.im/api/shorten?url=https://example.com` returns only the short URL.
- MCP (Model Context Protocol, Streamable HTTP): `https://skrat.im/mcp` with tools shorten_url, check_alias, get_link_info, qr_code.
- Auth: none required. Anonymous: 60 links/hour/IP. API key (`Authorization: Bearer skrat_…`, created at https://skrat.im/app/settings/): 1000/hour, links saved to the account.
- Anonymous links return an `edit_token` once; send it as `X-Edit-Token` to edit (PATCH) or delete (DELETE) `/api/v1/links/{id}`.

## Inspecting a short link

- `https://skrat.im/{alias}+` shows the destination, creation date and public click count as HTML.
- `https://skrat.im/{alias}.json` returns the same as JSON.
- `https://skrat.im/{alias}.png` and `.svg` return the QR code (query: size, fg, bg, margin).
