What is Payaion
Payaion is a secure file transfer service built on decentralized storage infrastructure. It allows anyone to upload a file, generate a shareable link, and deliver it instantly — without creating an account.
Without an account, an upload can be up to 100 MB and stays available for 24 hours before it is removed automatically.
Want more control? An account (wallet or Google login) raises the ceiling to 500 MB per file with 30 days of retention, and unlocks upload history, file management, and API keys for automation.

How it works
Upload a file from the home page. You'll get a share link that anyone can use to download the file. It stays alive as long as the file does — 24 hours for a guest upload.
For automation and integrations, use the Aion API or the MCP server with an API key from your dashboard. You can also list files on the marketplace for paid downloads.
Choose your path
There are three ways in: the quick transfer with no account, a dashboard account for history and higher limits, and the Aion API or MCP server for agents and automation.
