Ordnance Survey

Ordnance Survey is Great Britain's national mapping agency, a government-owned company that maintains the addressing and mapping layer the UK property market runs on - the Unique Property Reference Number (UPRN), the TOID, AddressBase, and the OS National Geographic Database. The UK has no MLS; residential listings sit behind the Rightmove/Zoopla duopoly and agency CRM software, so the open layer in this market is public-sector rather than private, and OS is one half of it alongside HM Land Registry. Its API posture is unusually honest for this sector - the OS Data Hub is a self-serve developer portal with real machine-readable contracts, including OGC-conformant OpenAPI 3.0 documents served live and anonymously at api.os.uk for OS NGD API - Features and Tiles, plus published OpenAPI for the OS Downloads and OS Net APIs. The split that matters is licensing, not reachability: OS OpenData products (OS Open UPRN, OS Open TOID, Code-Point Open, OS Open Names, Boundary-Line, OS Open Linked Identifiers) are free and downloadable with no API key at all through the OS Downloads API, while the premium addressing and mapping products behind OS Places API, OS Features API, and the NGD collections require a paid Premium plan or Public Sector Geospatial Agreement (PSGA) membership. RESO plays no part here - the Real Estate Standards Organization standards are a US MLS construct and appear nowhere in the OS estate. Home market is the United Kingdom.

Ordnance Survey publishes 25 API contracts indexed on the APIs.io network, including Bounding box API, Collections API, Data Collections API, and 22 more. Tagged areas include Real Estate, United Kingdom, Land Registry, Geospatial, and Addressing.

The Ordnance Survey catalog on APIs.io includes 1 Spectral governance ruleset.

Ordnance Survey’s developer surface includes authentication, documentation, getting-started guide, SDKs, sandbox, changelog, API reference, and 59 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-11-06 · rubric v0.27.0
Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
  • Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
  • Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
  • Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

MarketPositionDepthRegistered MCP serverDeclares compatibility
Geospatial and Maps (OGC standards) standard 17.2 (thin) - 3
UK G-Cloud Suppliers (UK public-sector cloud procurement) standard 17.2 (thin) - 3

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

imageNote: The `image` property was removed on 2026-08-26. It had been copied verbatim out of a bootstrap template and pointed
  at an icon belonging to groq, not to this company. That asset returns HTTP 200, so the record rendered another company's
  brand rather than a broken image, which is why it went unreported (roadmap#153). No correct icon has been sourced yet. Shipping
  the wrong company's mark is worse than shipping none; re-run the icon backfill once a real asset exists.
