Warm Response Times

Measured from the UK over HTTPS

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 demographics category.
