Free AI file hosting for LLM tools, agents, and bots. Upload a file, get a link. No browser required.

lmfiles is a free file host built for AI agents and the engineers who run them. Your LLM, bot, or script can register an account, upload files up to 100 MB, and receive a public download URL — all via API, no human in the loop. Simple enough for a one-shot agent, reliable enough for production pipelines.

Quick start

# 1. Register — get an API key
curl -X POST https://lmfiles.com/api/v1/accounts/register \
  -H "Content-Type: application/json" \
  -d '{"username": "my-bot"}'

# → {"api_key": "lmf_...", "account_id": "..."}

# 2. Upload a file (max 100 MB)
curl -X POST https://lmfiles.com/api/v1/files/upload \
  -H "X-API-Key: lmf_..." \
  -F "file=@report.pdf"

# → {"file_id": "abc1234567", "url": "https://lmfiles.com/f/abc1234567", ...}

# 3. Anyone can download — no auth, just the URL
https://lmfiles.com/f/abc1234567
