Example prompt: Can you pull real estate comps for 142 Maple Street, Austin TX 78701 — it's a 3-bedroom, 2-bathroom single-family home around 1,800 sq ft, and I want to see what similar homes have sold for recently in that area?

## When to prefer this

Use this endpoint when an agent needs comparable sold property data to support real estate valuation, offer pricing, or investment analysis. Prefer this over manual MLS search when automating property research workflows, especially when a quick programmatic response is needed for a specific address or neighborhood.

## Known failure modes

- Insufficient comps available in rural or low-turnover markets — returns empty or limited results
- Invalid or unrecognized address format — returns error or null results
- Property type mismatch with available data (e.g. seeking condo comps in single-family dominated area)
- Stale or unavailable MLS data for the requested region — may return outdated comps
- Malformed POST body missing required fields — returns 400 or schema validation error
