Open GI

Open GI is a Worcester-headquartered insurance software house that has supplied the UK and Ireland general insurance market for more than 45 years, serving over 600 broker, MGA and insurer customers across personal and commercial lines. Its product estate spans the legacy Core policy administration system and the newer cloud Mobius platform — policy administration and client management, product management, Insurer Hosted Pricing (IHP and IHP+), Ratings, the Dynamic Pricing Tool, quote-and-buy websites, customer portals and a Partner Network of 150-plus insurers, aggregators, premium finance, payment and data-enrichment providers. Its API posture is honestly partner-gated. Mobius genuinely ships APIs — Open GI's own public release notes describe Client Checks / sanctions-check endpoints and an API-triggered custom-event call — but the Mobius Developer Portal is a customer-only surface whose URL Open GI does not publish, no developer, docs, api or partners subdomain resolves on opengi.co.uk, every /developers, /developer, /api and /partners path on the marketing site returns 404, and even the company's own API Terms of Use page is password-protected. There is no public self-serve developer portal, no downloadable OpenAPI or Swagger, no public sandbox, no published auth model and no ACORD reference anywhere on the public site; insurer connectivity is delivered through UK-market EDI messaging inside the platform and through pre-agreed Partner Network integrations rather than through an open API programme.

Open GI publishes 1 API on the APIs.io network. Tagged areas include Insurance, United Kingdom, Ireland, Broker, and Agency Management.

Open GI’s developer surface includes engineering blog, changelog, release notes, documentation, FAQ, support, and 17 more developer resources.

  name: Mobius APIs
  description: The API layer of Open GI's cloud Mobius broking platform. Open GI's public Mobius release notes document real
    API capability — a Client Checks API whose sanctions-check endpoints include a POST to initiate a sanction check for a
    customer, GET endpoints for automated and manual sanction-check matches, a GET for the detail of a specific sanction and
    a POST to update notes and overridden matches, plus the ability to trigger a Mobius custom event from an external system
    via an API call. Access is gated. Open GI states these APIs are consumed through the Mobius Developer Portal by existing
    "Mobius APIs users", the portal URL is not published anywhere public, no developer or docs host resolves under opengi.co.uk,
    and the company's API Terms of Use page is password-protected. No base URL, OpenAPI definition, authentication scheme,
    rate limits or sandbox are publicly documented, so none are recorded here.
