## 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-spoken-numeric-token-index-snapshot-compare-9932291d -d '<json body>'
```

Example prompt: Compare snapshot A and snapshot B of the spoken numeric token index in the Baumarkt media dataset and show me what changed between them.

## When to prefer this

Use this endpoint when you need to programmatically compare two point-in-time snapshots of a spoken numeric token index specific to the HALOWERK Baumarkt media dataset. Prefer this over manual diffing or generic comparison tools when the index is managed by HALOWERK and the token structure is specialized to spoken numerics in a retail media context.

## Known failure modes

- Invalid or missing snapshot identifiers return an error
- Snapshot not found for a given ID
- Mismatched index versions that cannot be compared
- Payment failure via x402 protocol blocks the request
- Malformed request body returns 400-level error
