Insurance Australia Group API Gateway (private)
IAG runs an Apigee gateway with brand virtual hosts api.iag.com.au, api.cgu.com.au, api.nrma.com.au and api.wfi.com.au (plus the non-production test-api.iag.com.au). Each answers every path, including /openapi.json, /swagger.json, /api-docs and /graphql, with an Apigee "Unable to identify proxy" fault (HTTP 404), and docs.iag.com.au returns HTTP 401. IAG publishes no API documentation or machine-readable contract; the proxies behind this gateway are internal or partner-only.
