Frequently asked questions
EIS Group scores F on the API Report Card. EIS markets OneSuite as API-first with 9,000+ open APIs, but there is no public developer portal, sandbox, or API reference to verify any of it. Access comes only under commercial agreement as a carrier customer or contracted systems integrator, with docs delivered via the customer portal.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial EIS Group API and MCP server so AI agents and internal tools can read and write EIS Group data. See the EIS Group integration docs at supergood.ai/docs/eis-group-api.
