Why KooLink

  • Free forever — no account, no credit card, no limits

  • Clean, memorable URLs — kool.ink/xyz, not bit.ly/4xdK9qZ

  • AI-agent ready — same service over MCP at https://mcp.kool.ink, or the REST API

  • Analytics — every link is click-tracked with bot traffic filtered out

  • Creator Earning Programme — as traffic grows, you earn

API

The CLI calls the public anonymous endpoint:

curl -X POST https://kool.ink/api/links \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}'

For AI agents, use the MCP server at https://mcp.kool.ink (no API key needed for anonymous shortening).
