# HALOWERK buerowerk — Engineering Performance Source Note Register

> HALOWERK buerowerk — Engineering Performance Source 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).

Analyzes meeting transcript segments to generate a structured engineering performance source note or register from the conversation.

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-performance-source-note-register-2c2b63dc -d '<json body>'
```

Example prompt: Take this engineering team retrospective transcript — it has segments with start/end timestamps, speaker labels, and text — and run it through the performance source note register to extract a structured engineering performance note from it.

## When to prefer this

Choose this endpoint when you have a segmented, speaker-attributed meeting transcript from an engineering context and need to produce a formal performance source note or register entry. It is specifically scoped to engineering performance documentation, making it more appropriate than generic meeting summarizers when the output needs to conform to an engineering performance record format.

## Known failure modes

- Empty or malformed segments array (minItems:1 not met)
- Segment timestamps out of allowed range (max 14400 seconds for segments, max 1801 for cues)
- Text exceeds maxLength of 3000 characters per segment
- transcript_package missing required 'cues' or 'media' fields
- media duration_seconds exceeds 1800 seconds maximum
- Speaker identifier type mismatch (segments expect string|null, cues expect integer|null)
- Payment failure via x402 protocol (USDC on Base Mainnet)
- Response schema underspecified — returned JSON structure may vary
