Usage patterns

Pattern #1

Autonomous collections

Agent monitors overdue invoices, sends WhatsApp reminders via send_message, generates Pix charges with create_pix_charge, and reconciles payments -- fully autonomous.

Pattern #2

Overnight fiscal reconciliation

Scheduled agent cross-references ERP orders with NF-e emissions using list_receivables, flags mismatches, and auto-corrects when confidence is high.

Frequently asked questions

All credentials are encrypted at rest with AES-256 and stored in an isolated vault per organization. OAuth2 tokens are automatically refreshed before expiry. Your agent code never sees raw secrets -- it receives scoped, short-lived session tokens.
