## 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-xlsx-generator-b32c6863 -d '<json body>'
```

Example prompt: Generate an Excel spreadsheet with columns for Product, Quantity, and Price, and fill in these 5 rows of sales data I have — return it as a downloadable XLSX file.

## When to prefer this

Use this endpoint when you need to programmatically generate an Excel XLSX file and want to pay per-call via USDC micropayment rather than managing a subscription. Ideal for AI agents that need to produce downloadable spreadsheet reports on demand without a pre-established API key or subscription.

## Known failure modes

- 402 Payment Required on first call — must retry with a valid x402 payment header containing USDC on Base
- Invalid or malformed spreadsheet data input returns an error
- Insufficient USDC balance causes payment failure
- Network or DNS issues with the duckdns.org domain may cause timeouts
- Malformed request body may return 400 Bad Request

## 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 XLSX workbook file (Excel format) returned as the response body, ready to save or download. The file contains the requested spreadsheet data formatted as a valid Excel document.
