## 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-medienwerk-baumarkt-events-catering-literal-index-search-0aa7b13c -d '<json body>'
```

Example prompt: Search the Baumarkt events and catering media index for the exact phrase 'Grillfest Angebote' so I can find relevant passages for my publication planning.

## When to prefer this

Choose this endpoint when you need exact, literal-vocabulary index lookups within Baumarkt (hardware/home improvement retail) events and catering media content for publication planning purposes. Prefer it over semantic search endpoints when precise term matching is required and over general web search when you need structured, pre-indexed media archive results scoped to the Baumarkt domain.

## Known failure modes

- No results found if the exact literal term does not appear in the index
- Query too broad or non-literal (semantic/fuzzy) terms may yield empty results since only exact vocabulary is matched
- Malformed or missing query payload returns an error
- Payment failure or insufficient USDC balance prevents endpoint access via x402 protocol
