description: '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.'

  name: Whitespace Platform API
  description: The Whitespace Platform API is a REST/JSON API over the full London-market subscription placing lifecycle,
    publicly described by an OpenAPI 3.0.0 document covering 113 endpoints across Risks, Data, Attachments, Documents, Activities,
    Comments, Labels, Lookup, Endorsements, Lines, Questionnaire, Summary, User and MI Report. It genuinely exposes QUOTE
    (quoteOnRequest, saveQuoteDetails, getQuoteDetails, showQuoteToBroker, declineQuoteRequest, markAsIndicative, notTakeUpQuotation)
    and BIND (createBindableQuote, draftToFirmOrder, markAsFirmOrder, writeLine, recordLine, requestWrittenLineSets, acceptWrittenLine,
    signSets, reSignSets) and ISSUE of the contract document (getExtendedMRC, export/pdf/{riskID}, documents/{docID}), plus
    post-bind endorsement handling. It does NOT cover FNOL or claims — Whitespace is a placing platform, not a claims system.
    The embedded Defined Data API (/api/v22.04/data and /api/v23.09/data) returns and verifies structured contract values
    tagged against MRC headings and an alternative ACORDGPM tagset. Documented servers are the Sandbox, Tess, Beta and Staging
    environments; production access is arranged separately with Whitespace Support. Authentication is HTTP bearer JWT using
    a service token issued by Whitespace Support to a contracted organisation, restricted to allowlisted IP addresses and
    expiring within one year — there is no self-serve key.
