## 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-sponsors-literal-index-e9129a86 -d '<json body>'
```

Example prompt: Search the HALOWERK podcast sponsor index for the exact keyword 'Athletic Greens' and return all matching sponsor index entries.

## When to prefer this

Use this endpoint when you need exact, literal keyword matching against a pre-built podcast sponsor index rather than semantic or fuzzy search. Ideal for precise brand name lookups, compliance checks, or verifying specific sponsor appearances in podcast media without ambiguity from synonym expansion.

## Known failure modes

- No matches found for the provided literal keyword — returns empty result set
- Keyword not provided or malformed request body — returns validation error
- Payment authorization failure via x402 protocol — endpoint returns 402 Payment Required
- Rate limiting or quota exceeded — returns error response
- Keyword too generic yields excessive results with no useful filtering
