What makes it fast
The architecture is designed for consistent low-latency responses under any load.
Scales With You
Whether you send 10 requests or 10,000, the platform scales automatically. No queues, no slowdowns, no capacity planning.
Rich Data, Delivered Fast
Demographics, housing, crime, schools and more returned in a single call. Complex data, simple response, single-digit millisecond reads.
Mobile-Ready Responses
Every response is compressed to minimise bandwidth. Fast on any connection, ideal for mobile apps and low-bandwidth environments.
Low Latency, Everywhere
Requests are routed through edge locations closest to you, so connections are fast no matter where you're calling from.
Test methodology
- Warm tests — Sequential requests with 200ms spacing after a warm-up request. Measured end-to-end over HTTPS including TLS negotiation.
- Cold start tests — Samples forced by mutating a Lambda environment variable to trigger a new container.
- Test postcodes — SW1A 1AA, M1 1AD, EH1 1BQ with the
demographicscategory.
