Sprift

Sprift is a United Kingdom property data aggregator, operated by Sprift Technologies Ltd and founded in 2016 by Matt Gilpin, that assembles up to 300 data points on more than 30 million UK residential properties from public and private sources — Royal Mail, Ordnance Survey, the Environment Agency, HM Land Registry, Ofcom, Historic England, Ofsted, Google Maps, the Valuation Office Agency and the ONS — and links every one of them to a UPRN, the UK's definitive property identifier. It sells that layer to estate and letting agents, surveyors, mortgage professionals, conveyancers and investors as shareable property dashboards, branded reports, Material Information packs, comparables, off-market prospecting and market intelligence. In a market with no MLS, Sprift occupies the aggregation seam: it does not own listings (Rightmove and Zoopla do) and it does not originate records (HM Land Registry and Ordnance Survey do), it enriches and resells the join between them. Its API posture is genuinely documented but commercially gated. A public, unauthenticated Swagger UI at sprift.com/dashboard/api-doc serves a real Swagger 2.0 contract (sprift.json, version 1.3.9, 27 paths, 76 definitions) for the v1 API at https://sprift.com/dashboard/api/v1, harvested verbatim here — that is the only machine-readable contract Sprift publishes. Every operation in it requires a SPRIFT-API-KEY header, and the API base returns HTTP 401 to anonymous callers. There is no self-serve signup anywhere: /dashboard/register and /dashboard/signup both return 404, pricing is not published, and Sprift's own knowledge base instructs prospective API users to email Customer Success with their company, use case and target systems for review, noting that access "may require an additional agreement depending on your subscription". A larger v2 API family is advertised on the Data and API product page with named endpoint paths, webhook alerts and bulk queries, but no contract for it is published and no host for it was confirmed. No RESO Web API or Data Dictionary certification, no OData service root or $metadata document, and no Universal Property Identifier appears anywhere in Sprift's surface — RESO is a North American, NAR-driven construct and the UK has no MLS to certify against. The UK's standards seam is instead the Open Property Data Association and its Property Data Trust Framework, of which Sprift claims founding and accredited membership. Sprift publishes no open data of its own; the open UK property layer belongs to HM Land Registry and Ordnance Survey, which are among its inputs.

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Sprift the way a machine reads it — 18 machine-readable artifacts across 7 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 — Sprift scores 46.2/100 (developing), with a separate agent-readiness read of 71/100 (agent native). 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.

How we profile Sprift

Each block below is one kind of artifact we hold for Sprift. 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 7

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.

Arazzo Workflows 6

Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

Multi-step API workflows described with the Arazzo specification.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

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.

Security Posture 2

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.

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.
