## 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-long-gap-review-worklist-snapshot-compare-bd78ed3d -d '<json body>'
```

Example prompt: Compare the current state of our long-gap review worklist against the previous snapshot and show me what changed — which items are new, which were resolved, and which are still pending.

## When to prefer this

Use this endpoint when you need to audit changes to a media review worklist over a significant time gap, particularly in German-language retail (Baumarkt) media contexts. Prefer this over generic diff tools when the data is already structured as a HALOWERK medienwerk worklist and you need domain-specific change detection with x402 micropayment billing.

## Known failure modes

- Missing or invalid snapshot references returns an error
- No prior snapshot exists to compare against
- Snapshots belong to different worklist contexts and cannot be compared
- Payment not received or x402 authentication failure
- Empty worklist results in trivial diff response
- Malformed request body returns 400-level error
