OnTheMarket Scraper

Scrape UK property listings for sale and rent from OnTheMarket.com — one of the UK's leading property portals. Extract price, address, bedrooms/bathrooms, tenure, EPC rating, photos, floorplans, full description, and agent details (name, phone, branch address). Supports location-based search with filters (price range, bedrooms, property type) and automatic pagination.

Strategy

This actor uses CheerioCrawler (plain HTTP, no browser) by extracting data from the __NEXT_DATA__ embedded JSON blob served in OnTheMarket's Next.js HTML. This is the cheapest and fastest approach — no browser rendering, no anti-bot bypass needed for standard use. The site serves server-side rendered HTML with all listing data pre-embedded in the __NEXT_DATA__ script tag.

Data surfaces used:

• Search results pages (/for-sale/{type}/{location}/): 30 listings per page with price, address, beds/baths, tenure, images, agent info, lat/lng
• Property detail pages (/details/{id}/): full description, EPC rating, floorplans, full-size images, detailed agent info (opt-in via scrapeDetails)

Why CheerioCrawler: OnTheMarket is a Next.js app that server-side renders all listing data into __NEXT_DATA__ JSON. No JavaScript execution is needed — the data is already in the HTML source. This makes CheerioCrawler ~10x faster and cheaper than Playwright.
