Zoopla
Zoopla Limited is one of the two dominant residential property portals in the United Kingdom, operating zoopla.co.uk alongside PrimeLocation under the Houseful group (formerly ZPG), which also owns the Alto/Jupix estate-agency CRM software and the Hometrack valuation and mortgage-risk business. In a market with no MLS and no cooperative listing standard, Zoopla sits at the demand end of the value chain — consumers search on the portal, and listings reach it from agency CRM systems rather than from a shared data pool. Its API posture reflects that position honestly: the old public Zoopla listings API on the Mashery-hosted developer.zoopla.co.uk portal has been retired and the site no longer serves a valid certificate, and the current developer documentation at developers.zoopla.co.uk states plainly that "the Zoopla listings API is no longer publicly available." What remains public is a small, real, machine-readable surface aimed at member estate agents and their CRM vendors — a Leads API for polling applicant and appraisal enquiries, a real-time lead Push service, and two product-activation APIs for Premium Listings and Weekly Featured Properties. The documentation and three Swagger/OpenAPI contracts are openly readable with no login, but credentials are not self-serve: you must already be a Zoopla member on a listings package, and client_id/client_secret are issued by Member Services after you send them a GPG public key. There is no RESO Web API or Data Dictionary certification, no OData $metadata document, and no Universal Property Identifier anywhere in Zoopla's stack — RESO is a North American construct and the UK has not adopted it. Zoopla publishes no open data; the open property layer in the UK belongs to the public sector (HM Land Registry Price Paid and Ordnance Survey), not to the portals.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Zoopla the way a machine reads it — 30 machine-readable artifacts across 3 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Zoopla scores 34.4/100 (thin), with a separate agent-readiness read of 34/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Zoopla
Each block below is one kind of artifact we hold for Zoopla. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 2
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Zoopla Products API
The Products API from Zoopla — 4 operation(s) for products.
Zoopla REST Endpoints API
The REST Endpoints API from Zoopla — 2 operation(s) for rest endpoints.
Postman Collections 1
A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.
Ready-to-run Postman collections for exercising this provider's APIs.
01. Products API
POSTMANOpen Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).
Leads API
OPEN COLLECTIONPremium Listing activations
OPEN COLLECTIONWeekly Featured Property (WFP) Activations
OPEN COLLECTIONEvent Specifications 2
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Zoopla, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
