## 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-podcast-production-literal-index-snapshot-compare-313f498c -d '<json body>'
```

Example prompt: Compare the podcast production literal vocabulary index snapshots from last Monday and today — show me what wording changed, appeared, or disappeared in coverage of podcast production topics between those two timestamps.

## When to prefer this

Choose this endpoint when you need a precise, literal vocabulary-level diff between two specific points-in-time snapshots of a podcast production media index — particularly when exact wording matters and semantic or fuzzy matching would obscure the signal. Prefer this over general search endpoints when the goal is change detection rather than current-state lookup.

## Known failure modes

- Invalid or non-existent snapshot timestamps return an error or empty diff
- Snapshot timestamps outside the available retention window may not be found
- Malformed request body or missing required timestamp parameters returns a 4xx error
- Payment failure via x402 protocol blocks request execution
- Rate limiting or quota exceeded returns a 429-style error
