## 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-b31eafdf -d '<json body>'
```

Example prompt: Compare these two versions of our board meeting notes — the baseline has the original transcript segments and notes with action items, topics, and decisions, and I want to see exactly what changed in the summary, action items, and open questions between the two versions.

## When to prefer this

Use this endpoint when you need to programmatically detect and surface the exact differences between two versions of structured meeting notes — particularly when auditing edits, verifying note accuracy against a source transcript, or tracking how action items and decisions evolved. Prefer this over generic diff tools when the content is structured meeting data (segments, action items with owners/due dates, decisions) and you need semantically meaningful change detection rather than raw text diffing.

## 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 returns schema error
- Action items exceeding 30 items or text exceeding character limits cause validation failure
- Malformed or unresolvable transcript package URL returns fetch error
- Payment not included or insufficient USDC returns HTTP 402

## Output

Returns a structured JSON diff of the two meeting note versions, highlighting changes in summary bullets, topics, decisions, action items (including owner and due date changes), and open questions between the baseline and the current transcript/notes.
