# Fulcrum

> Fulcrum is a cloud manufacturing ERP/MES platform for precision manufacturers (CNC machining, sheet metal fabrication, job shops). The Fulcrum Public API is a REST API for building integrations directly into a Fulcrum site — quoting, sales orders, jobs, scheduling, inventory, purchasing, and invoicing. Authentication is a site-scoped bearer JWT; errors follow RFC 9457 problem+json; list endpoints use offset pagination (Skip/Take).
