REST API Integration

For custom UIs and deep data integration, use our standard JSON API.

Authentication

All API requests must include your API key in the X-API-Key header or as a key query parameter.

curl -H "X-API-Key: YOUR_KEY" \\
https://postcodewise.co.uk/api/postcode/SW1A1AA

Standard Response

Abridged example — the full payload also includes geography, per-topic metrics, data_quality and source attribution. Scores are 0–10 and null when a dataset does not cover the postcode.
