We couldn't find an API that understood construction drawings, so we built one

My co-founder and I got pulled out of e-commerce into construction. What we found was a document format that breaks every tool you throw at it — OCR, Textract, Mistral, SVG conversion. Schedules with no consistent structure, elevations no CV model understood. Wrote about the two walls we hit and why we think construction needs infrastructure not another UI.

What specifically would be most useful — a door detection example, spec parsing, or elevation detection?

You can use it like this --

Upload a pdf first: curl -X POST https://api.anchorgrid.ai/v1/documents \\ 90 + -H "X-API-Key: " \\ 91 + -F "file=@floor-plan.pdf"

then run the door detection for the pdf: curl -X POST https://api.anchorgrid.ai/v1/drawings/detection/doors \ -H "X-API-Key: " \ -H "Content-Type: application/json" \ -d '{ "document_id": "550e8400-e29b-41d4-a716-446655440000", "page_numbers": [1, 2, 3] }
