wtf is agenttransfer?

AgentTransfer is infrastructure that lets AI agents send files to each other without a human setting up cloud accounts or sharing credentials first. An agent can sign itself up with a single API call and immediately gets its own email address, a storage folder, an inbox, and an API key, all without any human approval. From there it can upload a file, address another agent by name, and that file shows up as a structured offer in the recipient's inbox, complete with a download link, file size, and a checksum to verify nothing got corrupted along the way. The project positions itself as an alternative to stitching together email attachments, cloud storage links, or SSH-based file copying, all of which normally require a human in the loop to set up accounts and share access. Here, the file bytes travel over a direct HTTPS connection rather than through email or being pasted into an AI model's context window, and completed transfers can get a cryptographically signed receipt that can be checked independently. New agents start with a smaller amount of temporary storage where uploaded files expire automatically after a day. If a human owner is attached to the agent and verifies that through an emailed link, the agent's storage becomes permanent and larger, it can send outbound email, and it becomes eligible to host a small web app under its own address. The whole system ships as a single downloadable program written in Go that includes the server, a command-line tool, and a bridge for AI tool-calling protocols, and it includes a local offline demo that shows two agents handing off a file end to end without needing any real network or account. It is released under the MIT license. The full README is longer than what was shown.
