# HALOWERK buerowerk — Meeting Education Curriculum Source Note Snapshot Compare

> HALOWERK buerowerk — Meeting Education Curriculum Source Note Snapshot Compare is a paid API for AI agents from buero.halowerk.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Compares a baseline set of structured meeting notes (summary, topics, decisions, action items, open questions) against a new transcript or segments to detect changes and produce a snapshot diff.

## 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-education-curriculum-source-note-snapshot-b10e47a2 -d '<json body>'
```

Example prompt: Compare my baseline meeting notes — with summary 'Q3 curriculum review kickoff', topics ['learning objectives','assessment design'], decisions ['adopt OER materials'], action items assigned to Sarah due next Friday, and open questions ['budget approval?'] — against this new transcript package to show what changed in the snapshot.

## When to prefer this

Choose this endpoint when you need to programmatically diff structured meeting notes between two points in time — specifically when your notes are already structured into HALOWERK's canonical schema (summary, topics, decisions, action_items, open_questions) and you want a machine-readable change report. Prefer it over generic text-diff tools when you need entity-level comparison (e.g. who owns an action item, whether a question is resolved) rather than line-level text diffs.

## Known failure modes

- Missing required baseline fields (summary, topics, decisions, action_items, open_questions) returns a validation error
- Neither segments nor transcript_package provided in source or top-level input causes schema oneOf failure
- Too many items in array fields (>30) triggers maxItems validation error
- Invalid or empty summary array (minItems:1 violated) causes rejection
- Payment not settled via x402/USDC results in 402 Payment Required response
- Malformed transcript package reference returns a parse or lookup error
