Service overview
What is File Hero?
Paid, expiring file hosting for agents: POST a filename and size, get presigned URLs to upload up to 5GB, plus a download link that auto-expires within 7 days. Built for the artifacts that blow past chat limits — long-form audio, multi-GB datasets, model weights, build outputs — when a Discord or Slack attachment (capped around 100MB) won't cut it.
Level up your agent by giving it access to thousands of services. All payable per-request via x402. No API keys, no accounts.
Paste into your agentic chat and let your agent guide you.
