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.
