Connells Limited, trading as Connells Group, is the United Kingdom's largest estate agency and property services group, headquartered at Cumbria House in Leighton Buzzard, Bedfordshire, and a wholly owned subsidiary of Skipton Building Society. It states 1,200+ branches, 16,000+ colleagues, more than 80 local brands including Connells, Countrywide, Hamptons, Sequence, Bairstow Eves, Fox & Sons, John D Wood & Co, Gascoigne Halman and Blundells, roughly 115,000 property sales a year and about 10% market share, 165,000+ managed tenancies and £33bn+ of arranged mortgage lending. It occupies almost the entire residential value chain at once: estate agency, residential and corporate lettings, new homes, land and planning, auctions, surveys and valuations, conveyancing, mortgage services, asset management, affordable housing, EPCs and inventories, commercial agency and a research and consultancy practice. Its home market is the United Kingdom, where there is no MLS and no cooperative listing standard — residential stock reaches consumers through the Rightmove and Zoopla portal duopoly by way of agency CRM and website software rather than a shared pool, and Connells' own consumer property sites are built on the Homeflow platform. Its API posture is closed and undocumented. No developer portal exists: developer., developers., api. and docs.connellsgroup.co.uk do not resolve, and /developers, /api, /docs, /openapi.json, /swagger.json, /api-docs and /.well-known/openid-configuration return 404 on both connellsgroup.co.uk and connells.co.uk. It publishes no OpenAPI, no GraphQL, no AsyncAPI, no MCP server and no client SDK — the only first-party package on any public registry is a dormant npm colour-token file for its website. Probing on 2026-07-26 did, however, find a small live JSON surface underneath the consumer site at https://www.connells.co.uk/api: six anonymous read-only Next.js route handlers serving the branch finder, people directory, testimonials wall and place autocomplete, plus a seventh (/api/properties) that returns HTTP 500. These are undocumented internal website routes, not a product — unversioned, unsupported, rate limited by Cloudflare, capped at 12 records because no paging parameter works, and carrying application errors inside HTTP 200 bodies. Only connells.co.uk exposes them; the sibling brand sites redirect /api/* away. The group's 88-URL corporate sitemap contains no developer path — its one /developers/ page is addressed to property developers, not software developers. Integration is real but partner-only: Connells Survey & Valuation advertises delivering "totally integrated panel and risk management technology solutions to lenders" for the 40+ lenders whose valuation panels it manages, and reaches them through third-party platforms such as Cotality's LenderHub, while Countrywide Surveying Services' Geoconnect engine is described as connecting internal and external data sources through API integrations it consumes rather than publishes. There is no RESO Web API or Data Dictionary certification, no OData $metadata document and no Universal Property Identifier anywhere in the estate — RESO is a North American NAR/MLS mechanism and the UK has no MLS to certify against. Connells publishes no open data either; its research product, covering 88% of UK postcode areas from branch-level proprietary data, is sold through a brochure request and a contact form, and the genuinely open UK property layer belongs to the public sector (HM Land Registry Price Paid Data and Ordnance Survey), not to the brokerage.
Connells Group publishes 4 API contracts indexed on the APIs.io network, including Branches API, Locations API, People API, and 1 more. Tagged areas include Real Estate, United Kingdom, Property Listings, Brokerage, and Estate Agency.
The Connells Group catalog on APIs.io includes 1 Spectral governance ruleset.
Connells Group’s developer surface includes code examples, authentication, engineering blog, and 30 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Securities & Market Data regime (on an ambiguous tag, where no other regime matched), 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 does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% 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
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
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
Pagination+5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs
4 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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.
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 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.
