One call beats five

PropertyData's equivalent requires separate calls to /demographics , /crime , /schools , /prices , and /internet-speed . Each is a separate HTTP round-trip, a separate credit charge, and a separate failure mode. Postcode Profile batches all of them: one request, one charge, one response.

Single HTTP request: faster page loads and fewer points of failureAll six domains cached independently for warm responses

Counts as one API call in your usage quota, not six
