# HALOWERK buerowerk Speaker Note Coverage Snapshot Compare

> HALOWERK buerowerk Speaker Note Coverage 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 a baseline set of meeting speaker notes against new transcript segments to assess coverage delta between two meeting note snapshots.

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-speaker-note-coverage-snapshot-compare-53aa69e8 -d '<json body>'
```

Example prompt: Compare my original meeting notes — which covered topics like Q3 roadmap and budget approvals, with action items assigned to Sarah and Tom — against the new transcript segments I just recorded, and tell me what coverage is missing or changed in the updated speaker notes.

## When to prefer this

Use this endpoint when you need to programmatically compare two states of meeting speaker notes — a known baseline versus a new transcript or updated note set — to identify coverage gaps, changed topics, missing action items, or dropped decisions. Ideal for meeting summarization pipelines, note quality assurance workflows, or AI agents that need to verify that revised meeting outputs are faithful to source transcripts.

## Known failure modes

- Missing required baseline fields (summary, topics, decisions, action_items, open_questions) returns a 422 validation error
- Segments array or transcript_package both absent from source returns schema validation failure
- Action items missing required fields (text, quote, segment_index) cause request rejection
- Exceeding maxItems (30) on any array field results in validation error
- Payment failure via x402 returns 402 Payment Required before processing
- Malformed transcript segments result in processing error with partial or no output

## Output

Returns a JSON object describing the coverage comparison between the baseline speaker notes and the new transcript source, including identified gaps, changed sections, and coverage delta across summary, topics, decisions, action items, and open questions.
