## 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-interview-projects-literal-index-snapshot-compare-e7587ac9 -d '<json body>'
```

Example prompt: Compare the two snapshots of the 'Q3-Interviews' literal index — snapshot from last Monday and today's — and tell me which terms were added, removed, or changed between them.

## When to prefer this

Use this endpoint when you need to audit or track changes in a literal-vocabulary index across two points in time for interview-based media projects — particularly when vocabulary consistency, content coverage, or indexing completeness needs to be verified between editing sessions or publication stages. Prefer this over manual review or generic diff tools when the index is managed by HALOWERK medienwerk and snapshots are already stored in the system.

## Known failure modes

- Invalid or non-existent snapshot identifier returns an error or empty diff
- Snapshot identifiers belonging to different projects may produce meaningless or rejected comparisons
- Malformed request body causes a 400-level error
- Payment failure via x402 results in a 402 response and no data returned
- Rate limiting or quota exceeded returns a 429 error
