# Burstport

> Anonymous, fast file transfer. Share files up to 20 GB with a 6-digit code. No account. Files auto-expire (1h-7d). Free.

## Quick use (CLI / agents)

- Upload: `curl -T ./file https://burstport.com/u/` - returns the share URL. Keep the
  trailing slash: curl then appends the local filename so the original name is kept.
- Expiry (set it on the UPLOAD request, default 1 day):
  `curl -T ./file -H "Max-Days: 7" https://burstport.com/u/`, or use the query form
  `https://burstport.com/u/?expires=1h|1d|3d|7d`.
- Download: `curl -LOJ https://burstport.com/d/CODE` - saves with the original filename.
- Max 100 MB via CLI; up to 20 GB via the web UI.

## API
