## Tools (as reported by the server, not verified)

- `format\_detect`: Detect the geometry file format from a filename or URL. Returns the detected format name and whether it is currently supported. Use this to check format support before making a paid analysis call. No payment required. Privacy policy: https://caliper.fit/privacy
- `feature\_request`: Request a feature or format that Caliper doesn't support yet. Free, no payment required. Use this when you need a capability that Caliper doesn't currently offer — especially unsupported file formats \(STEP, IGES\) or analysis features not yet available. Requests are logged and used to prioritize deve
- `format\_auto`: Auto-detect geometry file format and extract metadata statistics. Accepts a 3D geometry file via URL or base64 and returns structured metadata: bounding boxes, triangle counts, manifold analysis, point cloud statistics, and more. This is a read-only analysis tool — it does not perform mesh repair, f
- `format\_stl`: Extract metadata from an STL file \(ASCII or binary\). Returns triangle count, bounding box, surface area, volume, manifold analysis \(watertight, open edges, non-manifold edges\), triangle quality metrics, vertex deduplication count, mean edge length, minimum bounding sphere, and a noise estimate deriv
- `format\_obj`: Extract metadata from an OBJ file. Returns vertex/normal/texcoord/face counts, triangle/quad/polygon breakdown, material and group counts, bounding box, surface area, and triangulation status. Payment via x402 \(USDC on Base\) or card via MPP \(Stripe\). See format\_auto for payment flow details. Privacy
- `format\_ply`: Extract metadata from a PLY file \(ASCII or binary\). Returns vertex/face counts, element properties, feature detection \(normals, colors, texcoords, intensity, curvature\), bounding box, centroid, and point cloud identification. Payment via x402 \(USDC on Base\) or card via MPP \(Stripe\). See format\_auto
- `format\_pcd`: Extract metadata from a PCD point cloud file. Returns point count, field definitions, data format, organization, viewpoint, feature flags \(RGB, intensity, normals, curvature\), bounding box, centroid, and point density estimate. Payment via x402 \(USDC on Base\) or card via MPP \(Stripe\). See format\_aut
- `format\_las`: Extract metadata from a LAS or LAZ point cloud file. Returns LAS version, point format, point count, scale factors, offsets, bounding box, classification counts, feature flags \(RGB, intensity, GPS time, waveform\), and VLR information. Payment via x402 \(USDC on Base\) or card via MPP \(Stripe\). See for
- `format\_gltf`: Extract metadata from a glTF or GLB file. Returns asset info, scene graph structure, mesh/material/texture counts, vertex and index totals, feature flags \(normals, tangents, texcoords, colors, joints\), primitive modes, and extensions. Payment via x402 \(USDC on Base\) or card via MPP \(Stripe\). See for
- `format\_batch`: Analyze multiple geometry files in a single batch request. Submit up to 10 files, receive a single quote, pay once, and get structured metadata for all files. Supports mixed formats. Read-only analysis — does not modify, convert, or repair files. Payment is required via x402 \(USDC on Base\) or card v
