OnTheMarket Property Scraper

Turn any OnTheMarket search into clean, structured property data. Search by UK location (with price, bedroom and type filters), or paste search-results URLs and property URLs — and get one flat row per property with price, bedrooms, bathrooms, address, coordinates, features, images and the full agent block. Flip on detail mode to add the full description, EPC rating, floor area, and nearby stations & schools.

Built for property-market research, price monitoring, lead generation and building UK real-estate datasets.

How it works

✨ Why use this scraper?

• Rich rows out of the box — ~25 fields per property from the search results alone: price, beds, baths, property type, address, latitude/longitude, features, cover image + gallery, days-since-added and the full agent block (name, phone, logo, URL).
• Three ways in — location slugs (a search is built for you), pasted search-results URLs, or direct /details/ property URLs. Mix them in one run.
• Every UK location — london, manchester, sw1, n3 … OnTheMarket resolves the slug server-side. Add for-sale/to-rent, price, bedroom and property-type filters.
• Full detail on demand — turn on Scrape property detail pages (or paste a property URL) to add the full description, EPC rating, floor area (sqm), postcode, nearby stations (with lines) and schools (with ratings).
• Skips the ads — injected "in-market" advertorial cards are filtered out, so every row you pay for is a real property listing.
• No brittle DOM scraping — reads OnTheMarket's embedded __NEXT_DATA__ JSON, so the output stays stable when the page layout changes.
• JSON, CSV, Excel or API — pipe straight into your sheet, BI tool or pipeline. Billed per property.

📥 Supported inputs

Input	Example	What it does
Location slug	london, manchester, sw1	Builds a search and paginates the results
Search URL	https://www.onthemarket.com/for-sale/property/london/	Paginates that search's results
Property URL	https://www.onthemarket.com/details/19723728/	Scrapes that single property in full detail

Not supported: anything behind a login, saved searches/alerts tied to an account, buyer/agent messaging, or sold-price history endpoints. The actor reads only public search-results and property pages.

⚙️ How it works

1. Classify every input — location slugs become search URLs; pasted URLs are sorted into search vs /details/ property pages.
2. Fetch each page with a real browser TLS fingerprint over a UK residential IP, so OnTheMarket returns the real page.
3. Parse the page's embedded __NEXT_DATA__ JSON — a search page yields 30 properties; the ?page=2, ?page=3 … sequence is followed automatically up to your limit.
4. Enrich each property from its detail page (when Scrape property detail pages is on): description, EPC, floor area, postcode, stations and schools.
5. Emit one flat, deduplicated row per property to the dataset.

❓ FAQ

Is scraping OnTheMarket legal? This actor collects only publicly available listing data. You are responsible for using the output in line with OnTheMarket's terms and applicable laws (including GDPR for any personal data such as agent contact details). Do not use it to spam or to build a competing listings service.

Do I need proxies? OnTheMarket serves UK-geolocated pages, so requests go through UK residential IPs. Paid runs use a built-in GB residential pool automatically; free-tier runs default to Apify Residential (GB).

How many properties can I get? As many as the search returns — pagination is followed automatically up to your maxItems/maxItemsPerSearch limits. A single London search exposes tens of thousands of listings across pages.

How do I get the full description, EPC and floor area? Turn on Scrape property detail pages, or paste /details/ property URLs directly (those are always fully detailed).

What's a "row"? One property. You're billed per property row emitted to the dataset.
