# EquipmentShare — T3OS Developer Platform

> EquipmentShare is a construction technology and equipment-solutions company (founded 2015, Columbia, Missouri) whose proprietary platform, T3, connects one of the largest mixed fleets in the US (349,000+ connected assets across 380+ locations). T3OS is the developer surface: a GraphQL ERP API (`es-erp-api`) with user-delegated OAuth2, workspace-installed API keys, and OIDC sign-in, backed by an Auth0 tenant. This llms.txt is generated by the API Evangelist enrichment pipeline from public developer material; the API itself is access-controlled (register an app via the T3OS dev portal).
