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 CMiC API and MCP server so AI agents and internal tools can read and write CMiC data. See the CMiC integration docs at supergood.ai/docs/cmic-api.
