Inputs
- Postcode (required) — The postcode to look up, in any common format (e.g., '90210', 'SW1A 1AA', 'K1A 0B1').
- Country (ISO 3166-1 alpha-2) (required) — The two-letter ISO country code representing the country of the postcode (e.g., 'US').
- Boundary Options — Optional parameters to include additional data: whether to include polygon geometry as GeoJSON, polygon precision level (low, medium, full resolution), language tag to translate division names, and whether to include a map of other translated names.
Output shape
a single JSON object per input containing the boundary details corresponding to the postcode
The output contains administrative boundary attributes such as id, name, subtype, country, region, population, Wikidata ID, latitude, longitude, bounding box, optional polygon geometry (GeoJSON), and a confidence score. Geometry and other names are included only if requested in boundary options. Each output is paired with the input item for traceability.
