## 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-logistics-return-literal-index-1d9d4b2b -d '<json body>'
```

Example prompt: Search the recorded logistics briefing for every timestamped instance of the exact phrase 'return authorization' or 'return planning' — I need to know exactly when those terms were spoken.

## When to prefer this

Choose this endpoint when you need to find exact, literal keyword occurrences with timestamps in logistics or return-planning audio content, and you want deterministic text matching without speaker diarization or acoustic analysis. Best suited for compliance auditing, script verification, or content indexing where precise wording matters.

## Known failure modes

- Motor/transcription pipeline failure causes the request to fail before settlement
- Invalid or inaccessible media source URL returns an error
- Keyword not found in transcript returns empty results
- Malformed request body returns a validation error
- Deepgram processing timeout causes failure

## How this service works

Timestamped source search for return planning wording; literal vocabulary only. Reuses exactly one existing qualified transcript-package request. Source audio leaves the server for the existing Deepgram processor; existing provider disclosure and cost/margin retained. Deterministic timestamps/text processing only; no acoustic VAD, speaker identity or specialist accuracy claims. Base motor quote plus0.001USDC; article fails before settlement if the motor fails.

## Output

Returns a JSON payload containing timestamped text matches from the searched transcript or audio source, showing the exact literal keyword occurrences, their start/end times, and the surrounding transcript context. No speaker identification or acoustic analysis is included.
