## 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-baumarkt-unknown-speaker-review-snapshot-compare-55bdd961 -d '<json body>'
```

Example prompt: Compare two snapshots of that unknown speaker review from our Baumarkt media feed and tell me what changed between them — I need a JSON breakdown of the differences.

## When to prefer this

Use this endpoint when you need to programmatically compare two captured states of an unknown speaker review in a Baumarkt (hardware/home improvement retail) media context and receive a structured JSON diff. Prefer this over manual review when you need automated change detection on unattributed speaker media content with pay-per-call pricing via x402.

- Snapshots that cannot be parsed or decoded return a processing error
