Caliper

Need to pull triangle counts, bounding boxes, or point cloud stats from 3D files without spinning up your own parser? This server accepts STL, OBJ, PLY, PCD, LAS/LAZ, and glTF/GLB files via URL or base64 and returns structured metadata: manifold analysis, surface area, vertex counts, material lists, classification breakdowns. It exposes tools like caliper_auto_stats for format detection and extraction, plus caliper_batch_stats for processing up to 10 files in one call. Files under 150KB are free with no auth required. Larger files cost $0.02/MB via USDC on Base or Stripe. Useful for validating CAD uploads, pre-flight checks in 3D pipelines, or quick geometry audits without heavyweight dependencies.
