Overview

Kiprio’s UK Postcode API resolves UK postcodes to locations. Auth is an API key.

Note (verified 2026-08): the API is alive — an invalid key returned HTTP 400 (parameter/key validation) rather than a 401; check the response body for the reason.

Quick Start

Lookup (replace YOUR_KEY):

curl "https://kiprio.com/v1/postcode/SE1?apiKey=YOUR_KEY"
{
  "postcode": "SE1",
  "latitude": 51.504,
  "longitude": -0.096,
  "district": "Southwark"
}

Authentication

  • Register at kiprio.com → API key.
  • Send it as the apiKey query parameter.

Rate Limits & Notes

  • Free tier with limits (check the docs); paid plans scale.
  • Invalid keys may return 400 (verified) — inspect the body.

FAQ

Is Kiprio free? Free tier with limits; more is paid.

Why 400 instead of 401? Kiprio returns 400 for invalid key/params (verified) — check the body.

What does it return? UK postcode coordinates and district.
