## 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-meeting-decision-snapshot-compare-5ea4ef11 -d '<json body>'
```

Example prompt: Compare this week's meeting transcript against last week's baseline notes — my baseline has decisions about Q3 budget approval and two action items owned by Sarah and Tom, and I want to see what changed in decisions, action items, and open questions, formatted as a Markdown diff report.

## When to prefer this

Use this endpoint when you need to compare two meeting transcripts or sets of meeting notes to detect what changed in decisions, action items, and open questions between a baseline and a follow-up meeting. It is specifically designed for structured meeting-diff workflows with Markdown output, making it ideal for accountability tracking, sprint retrospectives, and iterative negotiation analysis. Prefer it over general summarization endpoints when your primary goal is delta detection rather than standalone summarization.

## Known failure modes

- Missing required baseline notes fields (summary, topics, decisions, action_items, open_questions) returns a 422 validation error
- Neither 'segments' nor 'transcript_package' provided in baseline source causes a schema validation failure
- Transcript too long or too many items (>30 per array) results in truncation or rejection
- Payment not fulfilled via x402/USDC returns 402 Payment Required
- Malformed or unreadable transcript package format causes a processing error
- Empty or minimal transcripts may yield low-confidence or empty diffs
