# HALOWERK buerowerk — Meeting Owner-Targeted Handoff Snapshot Compare

> HALOWERK buerowerk — Meeting Owner-Targeted Handoff 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 meeting snapshot (notes + transcript) against a new transcript for a specific owner, identifying changes in action items, decisions, and open questions attributed to that owner.

## 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-owner-targeted-handoff-snapshot-compare-d2c543ae -d '<json body>'
```

Example prompt: Compare last week's meeting snapshot for Alice — baseline notes include her action items around the Q3 roadmap and open questions about budget — against the new transcript from today's follow-up call, and tell me what changed for her specifically.

## When to prefer this

Use this endpoint when you need to track changes in meeting outcomes, action items, or decisions scoped to a specific named owner between a known baseline meeting snapshot and a new transcript. It is ideal for accountability tracking, handoff verification, and change detection across meeting iterations — especially when the owner-targeted scope is important. Prefer this over a general meeting summarizer when you already have a structured baseline and need a precise diff rather than a fresh summary.

## Known failure modes

- Missing required baseline fields (source or notes) returns a validation error
- Owner string not matching any participant in the transcript may return an empty diff
- Transcript segments malformed or exceeding item limits cause schema rejection
- Invalid or missing summary array (minItems:1) triggers a 400 error
- Network or payment failure via x402 protocol returns 402 Payment Required
