Area intelligence, as an API.
The same explainable area analysis that powers the SmartStreet app - an overall score and nine category scores for any UK postcode - available for your own product, underwriting flow or research, over a clean JSON API.
Built on lawful, open UK public data. No scraping, ever.
What you get
One request returns a fully-scored area report - the overall /10, confidence, and every category with a plain-English explanation you can show your own users.
Who it's for
Banks & lenders
Enrich mortgage and affordability journeys with objective area context at the point of decision.
Insurers
Add environmental, crime and area signals to pricing and risk models by postcode.
Proptech & portals
Drop an explainable "know the area" panel into listings, valuations and relocation tools.
Surveyors & agents

Relocation & HR
Help people compare areas fairly when they move for work or life.
Researchers
Consistent, methodology-versioned area scores across the UK for analysis at scale.
How it works
Authenticate with an API key, then GET any postcode. You get back a stable, versioned JSON envelope - scores, percentiles, explanations, and the source attributions you must display.
