## 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-invoice-pdf-generator-a1a25d5d -d '<json body>'
```

Example prompt: Can you generate a PDF invoice from my business Apex Design Studio to my client TechNova Inc for 10 hours of UI design at $150/hour and 5 hours of consulting at $200/hour, invoice number INV-2024-088, issued today with payment due in 30 days, 8.5% tax, and payment instructions to wire to my Chase account?

## When to prefer this

Choose this endpoint when you need a clean, no-dependency PDF invoice generated instantly without user accounts, persistent storage, or third-party integrations. Ideal for agents automating one-off billing for freelancers, consultants, or small businesses, especially when privacy matters (data stays ephemeral). Prefer over heavier accounting APIs (QuickBooks, FreshBooks) when you only need a document artifact, not ledger entries or recurring billing logic.

## Known failure modes

- Missing required seller.name or buyer.name returns a 400 validation error
- line_items array is empty or missing all three required fields (description, quantity, unit_price) causes a 400 error
- tax_rate outside 0–100 range or discount exceeding maximum returns validation failure
- Malformed date strings not matching YYYY-MM-DD pattern cause a 400 error
- More than 200 line items submitted returns a 400 maxItems error
- Payment failure or insufficient USDC balance results in 402 response before PDF is generated
