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.

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 development.

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, format conversion, or boolean operations.
Supported formats: STL, OBJ, PLY, PCD, LAS/LAZ, glTF/GLB.
STEP and IGES support is planned.
Provide either file_url (preferred for large files) or file_b64
(for files under 200KB). Include filename for format detection if
using file_b64. When using file_url, the format is detected from
the URL path extension; filename is not required.
Files under 150KB are free. Larger files cost $0.02/MB via x402
(USDC on Base) or card via MPP (Stripe; adds $0.35 surcharge).
If payment is required, the response includes payment details.
Retry with the payment argument containing the payment proof.

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 derived
from planar region fitting.
Payment via x402 (USDC on Base) or card via MPP (Stripe). See format_auto
for payment flow details. Privacy policy: https://caliper.fit/privacy
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 policy: https://caliper.fit/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
