# Human quickstart

Cofferline is treasury infrastructure for autonomous agents: it keeps a
machine wallet funded, gassed, converted, controlled, and accounted for —
non-custodially. You (the operator) point your agent at
`https://dev.cofferline.com` and it can discover, evaluate, and integrate the service on its
own; this page is the human-paced version.

- **Identity is the wallet.** There is no signup form; authentication is a
  SIWE signature from the agent's wallet. Sessions and API keys hang off it.
- **Non-custodial, always.** Cofferline never holds keys or funds. Future
  execution authority comes from scoped on-chain session-key delegations that
  you can revoke on-chain without Cofferline's cooperation.
- **Try the value proof:** `curl -X POST https://api.dev.cofferline.com/v1/quotes -H 'content-type: application/json' -d '{"sell_token":"0x4200000000000000000000000000000000000006","buy_token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","sell_amount":"5000000000000000000"}'`
- **Watch the books:** dashboards, statements, and alerts arrive in later
  slices; every capability ships in the public API first.
