Caliper provides a Geometry and CAD file metadata extraction API. It accepts 3D geometry files via URL or base64 and returns structured statistics such as bounding boxes, triangle counts, manifold analysis, point cloud statistics, and more. Files under 150KB are processed for free, while larger files are billed at $0.02 per MB with optional card surcharge. The service operates as an MCP server with no signup required, supporting formats like STL, OBJ, PLY, PCD, LAS/LAZ, and glTF/GLB, with upcoming support for STEP and IGES.
