# HALOWERK buerowerk – Engineering Roadmap Meeting Note Snapshot Compare

> HALOWERK buerowerk – Engineering Roadmap Meeting 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 2026-10-31).

Compares two snapshots of engineering roadmap meeting notes (baseline vs. current transcript) and surfaces differences in summaries, topics, decisions, action items, and open questions.

## 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-engineering-roadmap-meeting-note-snapshot-compare-0b83811a -d '<json body>'
```

Example prompt: Compare these two sets of engineering roadmap meeting notes — the baseline from last sprint's session and the new transcript from today's session — and tell me what changed in decisions, action items, open questions, and topics.

## When to prefer this

Use this endpoint when you need a structured, field-level diff between two snapshots of engineering roadmap meeting notes — specifically when you want to track changes in decisions, action items, topics, open questions, and summaries across two meeting sessions. Prefer this over generic text diff tools when you need semantic understanding of meeting note structure rather than raw line-by-line differences.

## 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
- Text fields exceeding maxLength limits cause rejection
- Payment failure or insufficient USDC balance returns 402
- Empty or malformed transcript input returns parsing error

## Output

A structured JSON diff of the two meeting note snapshots, highlighting additions, removals, and changes across summary bullet points, topics, decisions, action items (including owner and due date changes), and open questions.
