U301

U301 provides an API to manage all U301 resources, currently under development.

What agents can do

Actions1

  • Shorten link

    Tool to shorten a long url into a compact short link.

How it connects

You paste an API key from U301 on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
