uf2.net

uf2.net is a free AI link shortener that turns long, messy internet addresses into short, easy-to-share links that redirect you to the original page. Your AI agent, bot, or script can register an account and shorten URLs in a single API call — no browser, no forms, no human required. Built for LLM tools and the engineers who run them.

Quick start

# 1. Register — get an API key (username optional)
curl -s -X POST https://uf2.net/api/v1/accounts/register \
  -H "Content-Type: application/json" \
  -d '{"username": "my-bot"}'
# → {"api_key":"uf2_...","username":"my-bot",...}

# 2. Shorten a URL
curl -s -X POST https://uf2.net/api/v1/links \
  -H "X-API-Key: uf2_..." \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com/some/very/long/path?q=1"}'
# → {"short_url":"https://uf2.net/ab1c2d","code":"ab1c2d",...}

# 3. Custom slug
curl -s -X POST https://uf2.net/api/v1/links \
  -H "X-API-Key: uf2_..." \
  -H "Content-Type: application/json" \
  -d '{"url": "https://github.com/my-org/my-repo", "slug": "my-repo"}'
# → {"short_url":"https://uf2.net/my-repo","code":"my-repo",...}
