Example prompt: Can you look up the French cadastral parcel details for parcel 75101000AI0002 — I need the section and the area in square meters?

## When to prefer this

Choose this endpoint when you need to programmatically retrieve official French cadastral parcel data — section, area, and parcel ID — without setting up a full account or subscription. Ideal for one-off lookups, property due diligence, or enriching a dataset of French land parcels at $0.01 per call via USDC on Base.

## Known failure modes

- Invalid or non-existent parcel ID returns an error or empty result
- Parcel not found in the cadastre database for the given commune/section
- Malformed query parameters result in a 400-level error
- Payment not processed (x402 payment required before data is returned)
- Network timeout on the upstream cadastre data source
