Feichuan API

Move files between people and agents

Use a REST API to turn temporary files into shareable delivery links for scripts, automations, and AI agents.

Start in three steps

Create an API key, upload a file, and return a link.

1. Upload a file

curl -X POST https://f.devtool.uk/api/v1/transfers \\
  -H "Authorization: Bearer fc_your_key" \\
  -F "[email protected]"

2. Receive a share link

{
  "share_url": "https://f.devtool.uk/s/123456",
  "code": "123456"
}

Browser upload → share_url → agent

API upload → share_url → user

Agent A → share_url → Agent B

Send a link, not a large file.
