## 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-buerowerk-interview-education-transcript-source-note-register-a035c307 -d '<json body>'
```

Example prompt: Register these interview transcript segments into structured source notes — I have 45 minutes of content with speaker labels, and the cues include start/end times and text for each speaker turn across 3 speakers.

## When to prefer this

Use this endpoint when you need to register, process, and extract structured notes from timed multi-speaker interview or educational transcripts, especially when segments include speaker attribution and precise timestamps. Prefer this over generic text processing endpoints when working with structured transcript cue formats from media recordings up to 30 minutes (for cue format) or 4 hours (for segment format).

## Known failure modes

- Missing required segment fields (start, end, speaker, text) causes validation error
- Segment end time not greater than 0 or exceeding 14400 seconds causes rejection
- Transcript cue media duration exceeding 1800 seconds causes rejection
- Empty segments array or exceeding 20000 items causes schema validation failure
- Text field empty or exceeding 3000 characters per segment causes rejection
- Payment failure via x402 protocol results in 402 response and no processing
