## 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-support-incident-literal-index-snapshot-compare-0422ecf1 -d '<json body>'
```

Example prompt: Compare my two support incident literal index snapshots and show me what entries were added, removed, or changed between them — I need to audit index drift for the past week's incident catalog.

## When to prefer this

Choose this endpoint when you need to programmatically compare two point-in-time snapshots of a support incident literal index to detect drift, validate updates, or audit coverage changes. It is purpose-built for literal (exact-vocabulary) index comparison rather than semantic or fuzzy diffing, making it ideal for compliance-style audits where exact term matching matters.

## Known failure modes

- Missing or malformed snapshot payload returns an error indicating invalid input
- Snapshot identifiers that do not exist or are out of bounds return a not-found response
- Caller-supplied bounding parameter outside allowed range triggers a validation error
- Oversized index payloads may result in a timeout or payload-too-large error
- Mismatched index formats between the two snapshots may return a format mismatch error
