## 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-support-escalation-source-note-snapshot-eb35faf8 -d '<json body>'
```

Example prompt: Compare these two versions of our support escalation meeting notes — the baseline has the original transcript segments and notes with summaries, topics, decisions, action items, and open questions, and I need to know what changed in the updated transcript: what new action items were added, which decisions changed, and whether any open questions were resolved.

## When to prefer this

Choose this endpoint when you need a structured, field-level diff between two snapshots of support escalation meeting notes — especially when you have a baseline set of notes (with transcript segments and structured note fields) and an updated version, and want to programmatically detect changes in action items, decisions, open questions, topics, and summaries. Prefer this over generic document diffing when working within a meeting intelligence pipeline that already produces structured note objects with typed fields.

## 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 the source object causes a schema oneOf validation failure
- Action items exceeding maxLength for text (1000) or quote (3000) fields are rejected
- More than 30 items in any array field (topics, decisions, etc.) triggers a validation error
- Payment failure or insufficient USDC balance returns a 402 response before processing
- Malformed transcript package or inaccessible URL returns a fetch or parse error
