}About the moneysupermarket.com API
The MoneySuperMarket API provides 2 endpoints for querying live UK mortgage data — retrieve current lowest rates grouped by product type and LTV band via get_lowest_rates, or run detailed product searches across lenders using search_mortgages with filters for property value, deposit, region, and fixed term. Each response includes per-product rate, fee, APRC, and monthly cost data drawn directly from MoneySuperMarket's comparison index.
What the API Returns
The get_lowest_rates endpoint returns current lowest mortgage rates segmented by product type — TwoYearFixed, ThreeYearFixed, FiveYearFixed, and Variable — and further broken down by loan-to-value (LTV) bands. The optional category parameter scopes results to FirstTimeBuyer, HomePurchase, or Remortgage journeys. Each rate entry includes product details and the enquiry parameters needed to fetch a full product listing.
Searching Mortgage Products
The search_mortgages endpoint accepts a broad set of filters: property_value and deposit_amount in GBP, region (England, Scotland, Wales, or NorthernIreland), journey_type, product_type (Fixed or Variable), fixed_term (TwoYears, ThreeYears, or FiveYears), and sort_by (MonthlyCost, InterestRate, or APRC). Results are paginated at 20 products per page, and the response includes pagesAvailable, totalProductsUnfiltered, and totalProductsFiltered so you can build pagination controls accurately.
Response Shape
Each product in the search_mortgages results array carries rate, fees, monthly cost, and lender details, alongside the enquiryId that ties back to a specific search session. The request object echoed in the response confirms which parameters were applied, which is useful for logging or reconstructing searches. Products are filterable at query time by product type and term length without requiring a separate API call.
Source and Coverage
MoneySuperMarket does not publish an official public developer API for mortgage data. Coverage is limited to UK mortgage products listed on the MoneySuperMarket comparison platform. Data reflects what is available at query time and may vary by region and category.
- Display a live best-rate table on a UK property portal, broken down by TwoYearFixed and FiveYearFixed LTV bands

- Alert users when rates drop below a threshold by polling get_lowest_rates for a given category
- Compare remortgage options by region, filtering to Fixed products and sorting by APRC
- Aggregate mortgage product counts across pages using totalProductsFiltered to size search result sets
- Pre-populate a mortgage comparison widget for Scotland vs England using the region parameter
- Track rate movements over time by logging the lowest rate per LTV band from scheduled get_lowest_rates calls
