## 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-manufacturing-quality-literal-index-snapshot-compare-9609df2a -d '<json body>'
```

Example prompt: Compare these two manufacturing quality literal index snapshots for me — here's the old version and here's the new one — and tell me exactly what changed between them in terms of literal index entries.

## When to prefer this

Choose this endpoint when you need a literal, vocabulary-exact comparison between two manufacturing quality index snapshots rather than a semantic or fuzzy diff. It is purpose-built for industrial quality documentation and applies strict literal matching, making it ideal for compliance audits, change tracking, and regulatory reviews where exact wording differences matter.

## Known failure modes

- Invalid or inaccessible document URL returns an error
- Base64 payload too large or malformed causes rejection
- Documents in unsupported formats fail to parse
- Identical snapshots return an empty diff with no changes flagged
- Network timeout on remote URL fetch
