Server instructions

Four Echelon keeps engineering files as geometry. Use extract_cad (or extract_cad_from_url) to turn STEP, IGES, DXF, PDF, SVG, or draw.io files into four-cad.extraction.v1 JSON: solids, drawing entities, dimensions, annotations, and for draw.io a diagram2d graph with absolute node geometry, containers, directed connectors, and spatial relations. Use rowe_respond to ask Rowe spatial questions (understand, compare, fit, stability, placement, ...) over a cad_scene or point_cloud_scene. Every call is billed exactly like the REST API under the caller's API key.

Known tools 5

extract_cad

Four Cad extraction.

Inferred read-only

extract_cad_from_url

Same as extract_cad, but the server downloads the file from a public http(s) URL first (max 25 MB, 20 s).

Inferred read-only

rowe_respond

Rowe 1.0 spatial reasoning over structured geometry.

Inferred read-only

list_models

GET /api/v1/models: the public model list with pricing, supported tasks, input modalities, and whether the desktop inference runtime is available right now.

Inferred read-only

list_supported_formats

The file extensions extract_cad accepts, the target contracts, and the size limit.

Inferred read-only
