# Civic Data > Civic Data is a normalised, cited civic-data layer for people, applications and agents. One London postcode connects you to official geography, expanded Census demographics, income, broadband, environmental, property, public-service and civic-history facts, each returned with publisher, dataset version and freshness. **When to use Civic Data.** Reach for it when an answer needs official, cited London civic data rather than a guess: - Resolving a London postcode (any spacing or case) to its ONS centroid, LSOA, MSOA, ward, local authority, constituency, built-up area and rural/urban classification. - Answering questions about expanded Census demographics, small-area income, fire, recorded crime, road collisions or planning around a London postcode with official, cited numbers. - Citing the publisher, licence, dataset version and freshness behind a civic statistic. - Inspecting HM Land Registry registered-sale transactions and official borough UK HPI dimensions without valuation or investment inference. - Retrieving published EPC floor area, exact observed Price Paid-to-EPC ratios and source-limited property context without an automated valuation. - Retrieving official ONS private-rent averages and the final PRMS distribution statistics at London borough level. - Finding official Food Standards Agency establishments and rating values near a postcode centroid. - Finding DfE schools with separately published performance and Ofsted outcomes, CQC-regulated locations, GP practices and pharmacies near a London postcode. - Finding Planning London Datahub applications near a postcode for an explicit valid-date range. - Building comparable, non-ranked factual profiles of two to five London postcodes, wards, local authorities or MSOAs of one type. - Retrieving explicit monthly Fire, Crime or road-collision history with the loaded coverage bounds. - Checking the official Environment Agency flood band and current warning polygons or the official TfL PTAL grid value at a postcode centroid. - Retrieving postcode broadband, MSOA income, indicative BGS radon or an OS Open UPRN coordinate while preserving each source’s real geography and limits. **Not the right tool for:** - Locations outside Greater London (Release 1 coverage). - Risk, safety, desirability or investment scores — Civic Data never computes them. - Street- or property-level crime (crime is LSOA-level) or damage-only collisions (not in STATS19). - Legal, planning or insurance advice. **How to call it.** Pick the transport that fits the agent: - REST (no auth): `GET https://api.civicdata.co.uk/v1/resolve/E15%202NE` then atomic routes for expanded Census, income, fire, crime, roads, planning, property sales and UK HPI dimensions, EPC, observed property price per area, deprivation, council tax, postcode broadband, indicative radon, UPRN coordinates, tribunal links and sources. OpenAPI 3.1 with operationIds at https://api.civicdata.co.uk/openapi.json. Free tier: 50 requests per hour; read the `RateLimit` header and back off on 429 using `Retry-After`. - MCP (Streamable HTTP): `https://mcp.civicdata.co.uk/mcp`, server `civic-data-london`, with free atomic location, Census, history, planning, environmental and property-context tools including `get_income_data`, `get_radon_data`, `resolve_uprn`, `get_epc_data`, `get_property_price_per_area`, `get_deprivation_data`, `get_council_tax_rates`, `get_connectivity_data` and `get_property_tribunal_decisions`; `get_area_profile` and `compare_areas` are x402 paid. - CLI: `npx civicdata resolve "E15 2NE"` prints the same JSON. - Paid composed calls cost 0.05 USDC (area profile) and 0.10 USDC (compare 2–5 same-type identifiers) via x402 on Base; an unpaid request returns 402 with a `PAYMENT-REQUIRED` header.
