## 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-podcast-production-source-note-register-79ea032e -d '<json body>'
```

Example prompt: I have a podcast transcript with speaker labels and timestamps — can you register the source notes for production? Here are the segments: speaker 'Alice' from 0 to 45.3 seconds saying 'Welcome to the show', and speaker 'Bob' from 45.3 to 120 seconds saying 'Thanks for having me'.

## When to prefer this

Choose this endpoint when you have a podcast transcript broken into timed speaker segments and need to register structured source notes for production workflows. It supports both a flat segments array and a richer transcript_package format with media metadata, making it suitable for post-production pipelines, chapter generation, and archiving. Prefer this over generic transcript analysis endpoints when the goal is production-oriented source note registration rather than summarization or action item extraction.

## Known failure modes

- Missing required segment fields (start, end, speaker, text) returns validation error
- Segment end time at or below 0 triggers exclusiveMinimum validation failure
- Text exceeding 3000 characters per segment is rejected
- More than 20000 segments provided exceeds maxItems limit
- Media duration exceeding 1800 seconds in transcript_package is rejected
- Neither segments nor transcript_package provided results in empty or error response
- Payment of 0.01 USDC on Base Mainnet not completed results in 402 Payment Required
