## 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-baumarkt-engineering-security-literal-index-search-4414fe00 -d '<json body>'
```

Example prompt: Search the HALOWERK baumarkt media index for literal mentions of 'Brandschutzanforderungen' in engineering and security passages — I need the exact wording from timestamped sources, not paraphrases.

## When to prefer this

Choose this endpoint when you need exact, literal vocabulary matches from timestamped baumarkt/construction media sources specifically in the engineering and security domain — not semantic or fuzzy search, but precise index lookups. Prefer it over general web search when provenance, timestamps, and verbatim phrasing from curated hardware-industry sources are required.

## Known failure modes

- No literal matches found for the supplied vocabulary term — returns empty result set
- Query term too broad or ambiguous for literal index lookup — may return zero results
- Rate limit or payment failure via x402 protocol — call rejected before execution
- Invalid or malformed request body — returns error without search results
- Source index temporarily unavailable — service error response
