## 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`):

Example prompt: Can you generate a credit note PDF for a refund of $150 against invoice INV-2024-0042, issued to Acme Corp, with two negative line items: a $100 refund on consulting services and a $50 refund on travel expenses?

## When to prefer this

Choose this endpoint when you need a formally formatted, printable A4 credit note PDF with negative-line item support and a refund slip — particularly for accounting workflows, accounts payable corrections, or customer-facing refund documentation. Prefer this over plain invoice generators when the document must represent a credit or negative amount against an existing invoice. It requires no account or API key, only a per-call USDC micropayment.

## Known failure modes

- Malformed or missing request JSON body returns an error response
- Invalid or incomplete credit note fields (e.g. missing recipient or line items) may produce a malformed document
- Payment failure via x402/USDC prevents execution
- Network timeout from the Cloudflare Workers relay
- Unsupported currency or locale formats may not render correctly
