# info.summary
UK site intelligence API for architects, engineers, and urban planners.

# info.description
Atlasly's REST API for programmatic access to the 17-step site intelligence pipeline. Returns structured JSON for site analysis, planning constraints, flood risk, walkability, planning history, precedents, and CAD/BIM export generation. Used by AEC firms for batch site screening, PropTech platforms for listing enrichment, and academic institutions for site-level research.

For conversational use, install the Atlasly MCP server at https://mcp.atlasly.app/mcp — works with Claude, ChatGPT, and any MCP-compatible AI client.

# paths./site/{id}/export/{format}.get.summary
Download a CAD / BIM / GIS export for a completed site

# paths./site/{id}/export/{format}.get.description
Returns a signed URL or the file bytes directly, depending on the format. All exports are georeferenced (EPSG:4326) with named CAD layers. CAD / BIM formats (DXF, DWG, SKP, IFC, GLB, OBJ, FBX, STL, Collada) require the Professional plan.

# paths./site/{id}/export/{format}.get.responses.302.description
Redirects to a signed URL for the export file

# paths./compliance/check.post.summary
NPPF + local plan compliance scan on a proposal

# paths./compliance/check.post.description
