## 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 relaystation-invoice-pdf-generator-6869b005 -d '<json body>'
```

Example prompt: Generate a professional invoice PDF for my client Acme Corp — include two line items: 'Web Design' at $1,200 and 'Hosting Setup' at $300, with a total of $1,500, my company name 'Bright Studio', and invoice number INV-2024-042.

## When to prefer this

Choose this endpoint when you need a fast, programmatic, per-call invoice PDF generation without managing a full invoicing platform. It is ideal for agents automating billing workflows, freelancers generating one-off invoices, or SaaS products that need branded invoice PDFs on demand. At $0.0002/call (1¢ x402 minimum), it is cost-effective for both low and high invoice volumes.

## Known failure modes

- Malformed or missing JSON fields (e.g. absent line items array) returns a 400 validation error
- Missing required branding or totals fields may produce an incomplete or rejected render
- Overly large or complex invoice data may cause timeout or truncation
- x402 payment failure or insufficient USDC balance prevents the call from executing
- Invalid or unsupported currency symbols in line items may cause rendering errors
