PaidPilot Invoice API
PaidPilot Invoice API: Draft a payment reminder email (friendly, firm or final notice). Returns subject + plain-text body for an unpaid invoice, days overdue, the recommended tone and the next step. Template-based, deterministic. Draft only: this API never sends email.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
