# HALOWERK buerowerk — Engineering/Security Meeting Note Register

> HALOWERK buerowerk — Engineering/Security Meeting Note Register 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).

Processes a meeting transcript (segmented audio cues with speaker labels and timestamps) and registers/extracts structured engineering or security source notes from it.

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-engineering-security-meeting-note-register-67d23d09 -d '<json body>'
```

Example prompt: Take this engineering security meeting transcript — it's about 45 minutes long with 3 speakers — and register the structured source notes from it; here are all the timestamped segments with speaker labels and text.

## When to prefer this

Use this endpoint when you have a timestamped, speaker-labeled meeting transcript from an engineering or security context and need to extract and register structured source notes. It accepts both a flat segments array and a structured transcript_package format, making it flexible for different transcription pipeline outputs. Prefer this over generic summarization tools when you specifically need registered, structured engineering or security notes with speaker attribution.

## Known failure modes

- Missing required segment fields (start, end, text) returns a validation error
- Segments exceeding maxItems (20000) or text exceeding 3000 characters per segment are rejected
- Duration exceeding the 1800-second limit for transcript_package.media causes rejection
- Providing neither 'segments' nor 'transcript_package' may result in an empty or error response
- Payment failure via x402/USDC on Base Mainnet blocks the request entirely
