0 Finance

CLI-first banking for AI agents. Give your agents access to a bank account to create invoices, propose bank transfers, and match receipts purely from the CLI. Forkable and self-hostable.

Agent Capabilities

0 Finance gives agents a real bank account with a CLI-first workflow:

• CLI-first banking - Every workflow is scriptable via the zero CLI.
• Invoices - Create and send invoices from the terminal.
• Bank transfers - Propose ACH/IBAN transfers with approval gates.
• Receipt matching - Attach receipts to transactions and reconcile via CLI.
• Optimize yield - Idle funds auto-earn higher yield.
• Forkable - Run your own instance or customize workflows.

CLI Quick Start

CLI-first banking for agents starts with the zero CLI.

curl -fsSL https://zerofinance.ai/install | bash

# Authenticate (agent-native API flow)
zero auth agentlogin \
  --email finance-agent@acme.com \
  --company-name "Acme Inc" \
  --admin-token $ZERO_FINANCE_ADMIN_TOKEN

# Note: defaults to creating one Ethereum wallet when wallets are not specified

# Or browser login for humans
zero auth connect

# Or: zero auth login --api-key sk_live_xxx

# Check balance
zero balance

The CLI package is agent-bank, and the binary is zero (alias: zero-bank) for agent workflows.
