## 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-subscription-literal-index-3fdaa02c -d '<json body>'
```

Example prompt: Search the podcast subscription index for all entries containing the exact phrase 'machine learning' and return the matching segments with their timestamps.

## When to prefer this

Choose this endpoint when you need precise, literal keyword matching against a podcast subscription index — situations where semantic or fuzzy search would introduce unwanted noise and exact vocabulary matching is required. Prefer this over general podcast search APIs when working within the HALOWERK media pipeline and when you need structured, timestamped index results from a bounded subscription corpus.

## Known failure modes

- No results found if the literal keyword does not appear in the indexed content
- Invalid or missing keyword parameter returns an error
- Subscription index unavailable or empty returns empty result set
- Malformed request body returns a 400-level error
- Payment failure via x402 protocol prevents endpoint access
- Rate limiting or quota exceeded results in rejection
