## 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-notes-snapshot-compare-a306e033 -d '<json body>'
```

Example prompt: Compare my baseline clinical appointment notes — which include summaries, topics, decisions like 'patient approved for MRI', action items assigned to Dr. Müller due 2025-08-01, and open questions — against the new transcript segments from today's follow-up session, and show me what changed.

## When to prefer this

Use this endpoint when you need to programmatically compare a known baseline set of meeting or clinical appointment notes against a new transcript to surface deltas — specifically when you have structured baseline notes (with typed fields like action items with owners and due dates) and need a machine-readable diff rather than a simple text comparison. Prefer this over generic text-diff tools when your notes are structured clinical or meeting documents with semantic fields.

## Known failure modes

- Missing required baseline notes fields (summary, topics, decisions, action_items, open_questions) returns validation error
- Neither 'segments' nor 'transcript_package' provided in source or top-level input causes schema rejection
- Action item text or quote exceeding maxLength limits returns 400
- Empty summary array (minItems: 1 not met) causes rejection
- Payment failure via x402 returns 402 with payment requirements
- Malformed transcript package or segment references cause processing errors
