## 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 halowerk-medienwerk-word-csv-export-snapshot-compare-1c73f9ce -d '<json body>'
```

Example prompt: Compare these two contract drafts — the original at https://example.com/contract-v1.docx and the revised one at https://example.com/contract-v2.docx — and export the differences as a Word document so I can share the redline with my team.

## When to prefer this

Choose this endpoint when you need a structured, downloadable export (Word or CSV) of differences between two document snapshots — ideal for creating shareable redline documents, audit trails, or tabular change logs. Prefer this over plain text comparison endpoints when the output must be formatted for human consumption in office tools or spreadsheets.

## Known failure modes

- Unsupported document format returns an error indicating the file type cannot be processed
- URL fetch failure if document URLs are inaccessible, private, or exceed size limits
- Invalid base64 encoding causes a parsing error
- Both inputs identical returns an empty diff or minimal change report
- Payment not settled via x402 results in a 402 Payment Required response
