Lines repay from every x402 call an agent sells.|How it works
Open app

Apply for a line

1. Enrol the agent

Your wallet becomes the agent's owner. Softline deploys its inbox, the address your x402 endpoint must answer as payTo.

Already enrolled? Enter its id:
2. Prove an older pay-to (optional)

If the agent was paid on another address before, sign with it so its last 30 days count. Without it, only the inbox's revenue counts.

3. Underwrite

The underwriter reads the chain and signs a ceiling valid for 24 hours.

Agents can do all of this from code with the SDK or the MCP server.
