}Three endpoints, one schema
Lookup, batch, or risk-only. Each call returns the same field shape so model code stays unchanged when you switch.
GET /api/postcode/{postcode} Single postcode lookup. Returns the full feature vector with provenance and as-of dates per group.
POST /api/postcode/batch Up to 1,000 postcodes per call. Same field shape as the single endpoint, returned as an array.
GET /api/postcode/{postcode}/risk Risk-only subset. Crime rates, deprivation deciles, flood zone, and a composite score. Cheaper per call.
Where teams use it
Postcode features sit alongside the features you already have, in models you already run.
Lead qualification
Score inbound enquiries before sales picks up the phone. Use deprivation deciles, income proxies, and access scores as model features.
Insurance pricing
Add postcode-level risk signals to motor, home, and contents pricing models without licensing a separate dataset.
Fraud and KYC
Flag postcodes that diverge from a customer's declared profile. Crime trend, mobility, and demographic mismatches make useful features.
Catchment and site selection
Quantify catchment for retail, healthcare, or service sites. Build models on access times, household composition, and density.
Mortgage and credit risk
Use property mix, EPC ratings, and IMD income sub-domain to enrich credit decisions. Postcode features sit alongside applicant features.
Geographic experimentation
Stratify A/B tests by postcode profile so you can read effects across deprivation deciles or rural-urban splits.

Questions buyers ask
Does it cover Northern Ireland?
No. Coverage is Great Britain only. NI uses a separate postcode authority and deprivation framework, and several of the upstream sources do not extend there. Get in touch if you need NI and we will scope it out.
How fresh is the data?
Crime and Land Registry pricing refresh monthly. Connectivity and Open Roads refresh twice a year. Census-derived columns are decadal. Each response includes an as_of block per group so you can audit freshness directly.
Is any of it personal data?
No. Every column is a postcode-level aggregate. The smallest unit attributed is the postcode itself, around 15 households on average. Nothing in the response identifies a person.
Can I license the full dataset rather than call the API?
Yes. We deliver the same schema as Parquet or CSV with monthly diffs. Pricing depends on the slice and refresh cadence you need.
Can I add custom features?
Often, yes. If you have a public source you want enriched onto every postcode (a flood model, a brand catchment, a custom risk score), we can add it as a private extension column for your account.
What about the open data licences underneath?
We respect each upstream licence. Most sources are OGL v3.0 with attribution. Ordnance Survey content is delivered under OS OpenData terms. Sources are attributed in every response and in our docs.
