## 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-education-assessment-literal-index-snapshot-compare-e8a45059 -d '<json body>'
```

Example prompt: Compare the current snapshot of the education assessment literal index against last week's baseline to show me any new subtitle display gaps or caption coverage changes in our media library.

## When to prefer this

Use this endpoint when you need to programmatically compare two discrete states of an education-assessment literal index for subtitle or caption coverage auditing, particularly when working within the HALOWERK medienwerk x402 paid API ecosystem on Base Mainnet and when literal vocabulary fidelity is the primary concern rather than semantic analysis.

## Known failure modes

- Invalid or missing snapshot identifiers returns an error response
- Snapshot not found if the referenced index version does not exist
- Caller-supplied parameter bounds exceeded causing a validation error
- Payment not processed via x402 protocol results in 402 Payment Required
- Malformed request body returns a 400 Bad Request
- Timeout if the index comparison computation exceeds service limits
