## 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 Baumarkt engineering accessibility media index for the exact term 'barrierefreier Zugang' and return all matching literal keyword clips with their timestamps.

## When to prefer this

Choose this endpoint when you need exact, literal keyword matching against Baumarkt engineering accessibility media content and require timestamped or padded cue clip outputs. It is specifically suited for compliance audits, training material extraction, or maintenance planning where precise vocabulary matching matters and semantic/fuzzy search would introduce noise. Prefer this over general semantic search APIs when the user supplies exact German or English engineering accessibility terminology they want matched verbatim.

## Known failure modes

- No matching passages found for the supplied literal keywords — returns empty result set
- Keyword query missing or malformed — returns 400-level error
- Payment not completed via x402 — returns 402 Payment Required
- Source media not available or index not yet built — returns 404 or 503
- Query contains non-literal (semantic/fuzzy) terms unsupported by this endpoint — returns error or empty results
