## 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-finance-ledger-source-note-snapshot-compare-bd4c38b3 -d '<json body>'
```

Example prompt: Compare last week's finance ledger meeting notes — which had summary 'Q3 budget review finalized', decisions about headcount freeze, and action item for Alice to submit forecast by Friday — against the new transcript I just uploaded, and show me what changed in topics, decisions, action items, and open questions.

## When to prefer this

Choose this endpoint when you need a structured, field-level diff between two snapshots of finance-domain meeting notes — especially when tracking how summaries, decisions, action items, or open questions evolved between consecutive meetings. Prefer it over generic text-diff tools when you need semantic awareness of meeting note structure (owners, due dates, segment references) rather than raw text changes.

## Known failure modes

- Missing required fields in baseline notes (summary, topics, decisions, action_items, open_questions) returns a validation error
- Neither segments nor transcript_package provided in source returns a schema validation error
- Items exceeding maxLength or maxItems limits are rejected
- Malformed or inaccessible transcript package URL causes processing failure
- Payment not fulfilled via x402 results in 402 Payment Required response
