EIS Group

EIS Group (EIS Ltd) is a United States core-systems vendor for insurance, founded in 2008 out of Exigen Insurance Solutions and headquartered in San Francisco, California. EIS sells the EIS Platform and EIS OneSuite — a cloud-native, microservices core suite covering customer management, policy administration, billing, and claims — across group benefits, property and casualty / general, protection, life and annuities, and pet insurance. EIS markets itself as API-first and claims thousands of open REST APIs (1,100 digital APIs announced in 2019, 9,000+ claimed for OneSuite) fronted by the EIS DXP API middleware, but none of that surface is public. There is no self-serve developer portal on eisgroup.com; the documentation host docs.eisgroup.com answers HTTP 401 behind an HTTP Basic realm named "EIS Group Users", so the entire API reference is a customer/partner login wall. No OpenAPI, Swagger, GraphQL, AsyncAPI, or public Postman collection could be retrieved. The only public code EIS ships is two open-source GitHub repositories (kraken-rules, ui-render), which are libraries rather than APIs. ACORD is attested only indirectly — an analyst evaluation hosted on eisgroup.com states the system integrates using "web services, APIs, RESTful APIs, ACORD and certified ACORD" — with no ACORD artifacts, AL3 mappings, or IVANS/agency-download detail published. What EIS does publish is a substantial certification posture — a certified MACH Alliance membership (Microservices, API-first, Cloud-native SaaS, Headless) and a full ISO stack covering 27001, 27701, 22301, 27017, 27018, 27035-1, 12207, 15288, 25000 and ISO/IEC 42001, which EIS announced in June 2025 as the first cloud-native insurance core platform provider to obtain. One first-party package is public, eis-ui-render on npm. This is the canonical United States core-systems posture — the APIs exist and are sold, but they are reachable only through a licensed implementation.

EIS Group is profiled on the APIs.io network. Tagged areas include Insurance, United States, Core Systems, Policy Administration, and Claims.

EIS Group’s developer surface includes documentation, engineering blog, support, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/eis-group: open an issue to ask a question, or submit a pull request to add artifacts.
