Institutional data licensing, metered by API key

Every API key is provisioned with a specific set of scopes — a key can only ever call the endpoint groups it was granted, enforced on every request, not just documented.

Sandbox and live keys return the same real, aggregated data — sandbox mode exists purely so you can integrate and test without spending a live-key request quota.

This institutional dataset contains only property-level and aggregated figures. Tenant, buyer or other individual personal data is never included unless lawfully aggregated and anonymized beyond individual identification.
