# HALOWERK buerowerk — Meeting Action Items Snapshot Compare (CSV)

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

Compares two meeting note snapshots (baseline vs. updated) and returns a CSV-formatted handoff of action item differences

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-action-items-snapshot-compare-csv-607cb2bd -d '<json body>'
```

Example prompt: Compare the action items from our baseline meeting notes against the updated transcript and give me a CSV showing what changed — include owners and due dates from both snapshots.

## When to prefer this

Use this endpoint when you need a structured, CSV-ready diff of action items between two versions of meeting notes — especially useful for handoff workflows, project trackers, or change audits where downstream tooling expects CSV input. Prefer this over a plain meeting summarization endpoint when you already have a baseline snapshot and need to identify delta changes rather than summarize from scratch.

## Known failure modes

- Missing required 'summary' field in baseline notes returns validation error
- Neither 'segments' nor 'transcript_package' provided in source object causes schema rejection
- Action item arrays exceeding 30 items are truncated or rejected
- Malformed transcript package or inaccessible URL results in fetch/parse error
- Empty or whitespace-only text fields violate minLength constraints and return 400

## Output

A CSV-formatted comparison of action items between the baseline meeting notes and the updated snapshot, highlighting additions, removals, and modifications along with owner assignments, due dates, and the source transcript segments from which each item was derived.
