OnTheMarket Scraper - UK Real Estate API

Extract real estate listings from onthemarket.com, one of the UK's three major property portals. Returns rich structured data per listing: price, bedrooms, bathrooms, postcode, agent, full image gallery, and "recently added" status.

What you get per listing

• listingId, url — unique ID and direct link
• listingType — rent or sale
• propertyType — Flat, House, Studio, Maisonette, Bungalow, etc.
• title, address — listing headline + full address as published
• city, postcode — parsed from address (UK postcode regex)
• price (GBP, integer) — monthly for rent, total for sale
• priceText — as published (e.g. "£1,475 pcm", "Offers in excess of £500,000")
• priceQualifier — qualifier label if any ("Offers in excess of", "Guide price")
• bedrooms, bathrooms
• features[] — bullet feature list (e.g. "1 bedroom", "Garden", "Parking")
• agentName — listing agent or agency
• imageUrl, imageUrls[] — cover + full gallery
• isRecentlyAdded, daysSinceAdded — freshness signals from OnTheMarket
• currency (always GBP), scrapedAt

How to use

Easy mode (recommended): type a UK city name and pick listing type.

{
  "city": "London",
  "listingType": "rent",
  "maxItems": 200
}

Other examples:

{ "city": "Manchester",  "listingType": "sale", "maxItems": 100 }
{ "city": "Birmingham",  "listingType": "rent", "maxItems": 100 }
{ "city": "Edinburgh",   "listingType": "sale", "maxItems": 50  }
{ "city": "Bristol",     "listingType": "rent", "maxItems": 100 }

Power-user mode: for finer filters (price range, bedrooms, sub-area, property sub-type), set them on onthemarket.com, copy the URL from your browser, paste into searchUrl. The structured inputs are bypassed.

Common use cases

• Investor monitoring — track new listings across London, Manchester, Birmingham, Edinburgh; snapshot rent yields by postcode.
• Lettings agencies — pull competitor listings + agency activity for your market.
• PropTech analytics — supply, average price/bedroom, recently-added share by city.
• Lead generation — agentName aggregates the high-volume agencies in each market.

Data quality

In testing across London, Manchester, Birmingham, and Edinburgh (sample of 100+ listings, both rent and sale):

Field	Fill rate
price, priceText, propertyType	100%
address, city, postcode	100%
bedrooms	95-100% (some studios legitimately have no bedrooms value)
bathrooms	80-95% (not always published in the search response)
imageUrl, imageUrls	~99%
agentName	100%
isRecentlyAdded, daysSinceAdded	populated when OnTheMarket flags the listing as fresh

pricePerSqm is always null — OnTheMarket does not publish floor area in the search response.

Pricing

Pay per result. See the Pricing tab. Failed runs cost nothing.

Notes

• The actor uses Apify's residential proxy (UK) for reliable access.
• Pagination is automatic — set your desired maxItems and the actor walks through pages until it has enough or runs out.
• Postcode is extracted from the address using the standard UK postcode pattern (handles outward and inward codes including space-separated and concatenated forms).
