## 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-snapshot-compare-baumarkt-support-authentication-d9b6d274 -d '<json body>'
```

Example prompt: Compare the two snapshots in the baumarkt support-authentication literal index for the keyword 'Passwort zurücksetzen' and show me what changed between them.

## When to prefer this

Choose this endpoint when you need to compare two discrete snapshots of support-authentication passages within the HALOWERK baumarkt media index using exact literal keyword matching — not semantic or fuzzy search. It is purpose-built for auditing wording changes in bounded retail support documentation rather than general document diffing or full-text semantic retrieval.

## Known failure modes

- Keyword not found in either snapshot returns empty match set
- Invalid or expired snapshot identifiers return an error
- Index out of bounds if the caller-specified literal falls outside the bounded index scope
- Payment failure via x402 returns 402 status before processing
- Malformed request body returns validation error
