## 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-finance-forecast-literal-index-snapshot-compare-d943d300 -d '<json body>'
```

Example prompt: Pull a snapshot comparison on the finance-forecast literal index — I want to see what changed between the two most recent snapshots so I can audit coverage gaps in our financial media content.

## When to prefer this

Use this endpoint when you need to compare discrete states of a finance-forecast literal index — particularly for editorial audits, compliance reviews, or coverage monitoring workflows that require exact literal vocabulary matching rather than semantic search. Prefer this over general search endpoints when you need a structured diff of index snapshots rather than ranked retrieval.

## Known failure modes

- Snapshot not found for given reference returns 404-equivalent in JSON
- Malformed request body causes validation error
- Payment failure via x402 protocol blocks request execution
- Out-of-bounds or unavailable time range returns empty or error result
