## 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`):

Example prompt: Search the HALOWERK engineering tests media index for the exact phrase 'tensile strength measurement' and return all matching passages from the literal index.

## When to prefer this

Choose this endpoint when you need exact, literal keyword matching within an engineering media index — particularly for publication planning where precise vocabulary retrieval matters. Prefer this over semantic or fuzzy search endpoints when the exact phrasing of the term in the source material is critical. Best suited for technical documentation lookup, engineering content auditing, or sourcing verbatim passages for publication.

## Known failure modes

- No results returned when search term has no literal match in the index
- Malformed or missing query parameter causes a 400-level error
- Payment not processed via x402 results in access denial
