CLI-first bank account for AI agents with human-approved transfers
0 Finance is a CLI-first financial workflow project for agent-driven invoicing, transfer proposals, and human approvals. Its current site says the product is being deprecated and new signups are disabled. Agents and scripts use the zero command line tool to check balances, create and send invoices, propose ACH or IBAN transfers, and view savings positions. Read operations run immediately, while transfers and withdrawals become proposals that a person reviews in the companion web dashboard. The same primitives are reachable through an HTTP API and an MCP server for assistants. Accounts hold funds as USDC in self-custody wallets, with idle balances allocated to lending protocols for variable yield and smart-contract failures insured up to a stated limit. The hosted dashboard serves existing customers, and the MIT-licensed codebase can be forked and run independently with Docker. The vendor states the product is being deprecated and has disabled new signups. No public pricing is documented. A full independent deployment also needs credentials for third-party auth and payment providers, so self-hosting is nontrivial.
