Whitespace
Whitespace Software Limited is a London-based digital placing platform for the Lloyd's and London (re)insurance market, and one of only two electronic placing systems given fully recognised status by Lloyd's. Acquired by Verisk (via Sequel), Whitespace lets brokers and underwriters create, negotiate, quote, firm-order, line, sign and endorse fully digital subscription-market contracts in place of the traditional slip, across property and casualty, specialty, marine, aviation, energy and reinsurance business written in the United Kingdom and internationally. Its API posture is unusually strong for the insurance sector but only half open: the reference documentation is genuinely public and unauthenticated at apidocs.whitespace.co.uk, with a complete OpenAPI 3.0.0 description of 113 endpoints served through Swagger UI at swagger.whitespace.co.uk, yet there is no self-serve signup. Sandbox and production service tokens are issued by Whitespace Support to contracted broker, carrier and vendor organisations, are IP-allowlisted and expire within a year, so the integration surface itself is partner-gated. Whitespace is ACORD-native rather than merely ACORD-aware: it authored the JSON Market Reform Contract (JMRC) standard and donated it to ACORD for incorporation into the Global Reinsurance and Large Commercial data standards, and its Defined Data API returns contract values tagged with an ACORDGPM tagset alongside MRC headings. Event integration is delivered as per-client Azure Service Bus queues rather than webhooks, and no AsyncAPI, GraphQL or public Postman workspace is published.
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.
API Evangelist profiles Whitespace the way a machine reads it — 29 machine-readable artifacts across 1 API, 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 — Whitespace scores 46.8/100 (developing), with a separate agent-readiness read of 29/100 (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 Whitespace
Each block below is one kind of artifact we hold for Whitespace. 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 24
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.
Whitespace Activities API
The Activities API from Whitespace — 4 operation(s) for activities.
Whitespace Attachments API
The Attachments API from Whitespace — 7 operation(s) for attachments.

Open Collections 1
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).
Whitespace Platform API
OPEN COLLECTIONEvent 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.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Whitespace Platform Activity Queues

ASYNCAPISecurity 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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 Whitespace, 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.
