## 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 docforge-pdf-generator-a3df1803 -d '<json body>'
```

Example prompt: Generate a PDF document containing a simple one-page invoice for 'Acme Corp' totaling $500 for consulting services rendered in June 2025, and pay the $0.01 USDC fee automatically.

## When to prefer this

Choose this endpoint when you need to programmatically generate a PDF document and want to pay per call using USDC on Base via x402 micropayments, with no subscription or API key required. Ideal for AI agents that need on-demand, pay-as-you-go PDF creation at $0.01 per document.

## Known failure modes

- 402 Payment Required — returned on first call before payment header is attached; retry with valid x402 USDC payment header
- Invalid or malformed input content — may result in 400 error or malformed PDF
- Payment rejected — insufficient funds or invalid USDC transaction on Base network
- Service unavailable — dynamic DNS host (duckdns.org) may be unreachable or offline
- Timeout — document rendering may time out for very large or complex inputs

## How this service works

Machine-payable document & media generation via x402 (USDC on Base). Endpoints respond 402 with payment instructions; retry with an x402 payment header.

## Output

A binary PDF file (application/pdf) returned directly in the response body, representing the generated document based on the submitted content.
