## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability paidpilot-reminder-draft-3726c33c -d '<json body>'
```

Example prompt: Draft a firm payment reminder email for my client Acme Corp — invoice #INV-2081 for $3,450 USD was due on 2025-05-01. Sign it from Riverside Consulting, include this payment link https://pay.example.com/inv2081, and flag that late fees are 1.5% per month.

## When to prefer this

Choose this endpoint when you need a deterministic, template-based payment reminder email draft and do not need AI-generated creative copy or actual email delivery. Ideal for accounts-receivable automation pipelines, billing systems, or agents that compose and then send the email via a separate channel. Prefer over general-purpose LLM text generation when consistency, structured output (subject + body + metadata), and low per-call cost matter.

## Known failure modes

- Missing required fields (invoice_number, client_name, from_name, due_date, amount) returns a 422 validation error
- Invalid date format for due_date or as_of returns a 400 error
- amount <= 0 or exceeding maximum returns a 400 validation error
- Invalid tone enum value (not friendly/polite/firm/final) returns a 422 error
- payment_link not a valid URI returns a 400 error
- final_deadline_days outside 1–60 range returns a 422 error

## How this service works

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.

## Output

Returns a JSON object containing: a ready-to-use email subject line, a plain-text email body personalized with client name, invoice number, amount, and due date, the number of days the invoice is overdue, the tone applied (friendly/polite/firm/final), and a recommended next step for the sender. The draft is never transmitted — the caller is responsible for sending.
