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.
Whitespace publishes 24 APIs on the APIs.io network, including Activities API, Attachments API, Bind Notify Parties API, and 21 more. Tagged areas include Insurance, United Kingdom, Reinsurance, Property and Casualty, and Insurtech.
The Whitespace catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Whitespace’s developer surface includes authentication, documentation, API reference, support, engineering blog, CLI, changelog, and 29 more developer resources.
