Area coverage
GET /v1/areas/coverageThe data-coverage register for a local authority — read it before the data: per-field non-null and source shares over every unit in the authority (floor area, bedrooms, year built, EPC, last sale, tenure…), which designation flags were checked and how fully, how many units carry a registered lease or a hereditament, whether official planning data covers the authority and how deep it goes (applications, link shares, latest decision), and how much of the live listing stock the sweep has dated. `area` is a GSS code (E09000032), a local authority name (Wandsworth) or a warehouse area id. State the coverage before quoting a share from a thin field. UK only.

Price and licence
What it costs, and where the data comes from
Area coverage is free over MCP and over REST, and the two surfaces share one credit balance. Free calls need a signed-in account or an API key and appear in your usage, but they never touch your balance.
Credits are granted on sign-up and bought in packs; the pricing page lists every call.
FAQ
Questions about Area coverage
How much does `data_coverage` cost?
+
Area coverage is free over MCP and over REST, and the two surfaces share one credit balance. Free calls need a signed-in account or an API key and appear in your usage, but they never touch your balance.
How do I authenticate?
+
Send your API key as a Bearer token in the Authorization header. Keys are created in the API & MCP Hub, shown once and revocable. Every response carries the credits charged and your remaining balance.
Is there an MCP version?
+
Yes. The data_coverage tool on the MarketCode MCP server is the same call at the same price, signed in with OAuth rather than a key, so Claude, ChatGPT, Codex and Cursor can run it in a conversation.
Where does the data come from?
+
The answer is computed by MarketCode. Coverage is the UK.
Does `data_coverage` change anything?
+
No. The tool is annotated read-only on the server, so it never writes to your data or ours and an assistant can call it without a confirmation step.
