Area Sold Prices API

The Area Sold Prices API provides access to the complete Land Registry Price Paid dataset for any UK postcode area. Unlike the radius-based Sold Prices API, this endpoint queries directly from our database of millions of property transactions, supporting pagination, street-level filtering, and comprehensive query options.

Data included in the response:

• Individual sold prices — full address, price, date, property type, new build status, estate type (freehold/leasehold), street, town, district, and county
• Summary statistics — total results, average price, median price, price range, and breakdown by property type
• Pagination — offset-based pagination for iterating through large result sets

This API is ideal for:

• Bulk analysis of sold prices across an entire postcode area
• Market research tools comparing areas or streets
• Property investment analysis with granular filtering
• Data pipelines requiring paginated access to sold price data
• Street-level price analysis within an area

All requests to the Area Sold Prices API require authentication using an API key. You can obtain your API key from your PropertyInsights dashboard after subscribing to an API plan.

Successful chargeable JSON responses include a top-level billing object. The endpoint examples on this page focus on the endpoint-specific data, so this repeated block may not be shown in every example.

"billing": {

  "creditsCharged": 1,
  "creditsRemaining": 1999,
  "creditsRefreshAt": "2026-08-14T09:30:00.000Z"
}

All authenticated API-key calls expose the billing headers, including validation errors and zero-credit status or management requests. Only successful chargeable JSON responses add the billing object to the response body.
