Example prompt: Can you run a full investment scorecard on a 65 m² apartment at 12 rue de la Paix, Paris 75002 — I want the DVF price estimate, energy rating, natural risks, local demographics, and expected rental yield all in one go?

## When to prefer this

Choose this endpoint when you need a single aggregated investment scorecard for a French property, combining price, energy, risk, demographics, and rental yield in one call — rather than making separate calls to individual APIs for each data point. Ideal for real-estate due diligence, investment screening, or property comparison workflows in the French market.

## Known failure modes

- Address not found or ambiguous — returns error or empty result
- Address outside France — endpoint only covers French territory
- Missing required query parameters (adresse, surface, or type) — likely returns 400 or error payload
- Property type not one of 'appartement' or 'maison' — may return validation error
- No DVF comparables available for the area — price estimate may be absent or low-confidence
- Payment of $0.08 USDC not completed — returns 402 Payment Required

## How this service works

## Output

A structured investment scorecard including: DVF-based market value estimate (€/m² median and range), energy performance rating (DPE class), natural risk exposure indicators, local demographic data, and an estimated gross rental yield — all synthesized for the queried address and property type.
