Not official, property, resident, screening, or current-condition evidence. Charge-free on no match or source failure.

  - `latitude` number: Decimal latitude; provide with longitude to skip address geocoding.

## Other responses

- `400`: Invalid request body.
- `402`: Payment Required. For x402 v2, repeat the identical request with a valid PAYMENT-SIGNATURE header (legacy X-PAYMENT is accepted for compatibility). MPP is disabled for paid-only atomic research.
