Return a multi-axis, revenue-anchored business breakdown (Business Breakdown). Groups SEC XBRL segment facts into the canonical product, geographic, and operating axes, de-subtotals each axis against total reported revenue, and emits per-segment revenue share, profit/loss, margin, and YoY growth. Each axis is flagged reported or low\_confidence based on whether it ties to total revenue (banks, REITs, and insurers typically do not tie). Ships beta. Requires ticker or cik.

## Give this prompt to your agent

<Prompt>
  Use SEC API GET /v1/companies/segments to return a multi-axis, revenue-anchored business breakdown (Business Breakdown). Groups SEC XBRL segment facts into the canonical product, geographic, and operating axes, de-subtotals each axis against total reported revenue, and emits per-segment revenue share, profit/loss, margin, and YoY growth. Each axis is flagged reported or low\_confidence based on whether it ties to total revenue (banks, REITs, and insurers typically do not tie). Ships beta. Requires ticker or cik. Preserve `requestId`, `traceparent` in the output. Return a concise markdown summary plus the exact structured payload fields that a downstream engineer or agent should keep using this result.
</Prompt>

## Failure posture

* treat non-2xx responses as contract-aware failures, not free-form errors
* preserve `requestId` and `traceparent` in logs and downstream reports
* if provenance or freshness metadata is present, return it unchanged so trust is not lost in the handoff
