## When to prefer this

Use this endpoint when you need to identify and filter out invalid or expired decision legs in a financial or options strategy context, particularly when working with structured decision trees that require real-time validity checks. Prefer this over manual tracking or static lists when you need up-to-date invalidation data on a per-call basis.

## Known failure modes

- 400 Bad Request if required input fields are missing or malformed
- 503 Service Unavailable if the upstream data source is temporarily down
- Empty result set if no invalidations are currently recorded
- Timeout if the provider endpoint is slow to respond
