CustomerOS REST API
Key-authenticated REST surface for the customeros.ai cloud, published as six OpenAPI 3.0.1 documents (one per tag) plus the source Swagger 2.0 in github.com/customeros/customeros. All six declare the same ApiKeyAuth scheme, an X-CUSTOMER-OS-API-KEY header, and the same servers[] host https://api.customeros.ai. Access to each endpoint group is granted on a per-request basis by the CustomerOS team. NOTE: as of 2026-08-13 api.customeros.ai has no DNS address record, and the docs pages that used to document this API (docs.customeros.ai/api-overview and /api-descriptions) now return 404 — see lifecycle/customeros-lifecycle.yml.
