Upload export files into your human's workspace to build or rebuild their map; then call build_map. files: [{path, content, encoding?}]. path starts with the system folder (shopify/orders.csv, dinero/postings.csv): the folder name becomes the system in the map, so leave out a shared root folder. content is the file as text (CSV, JSON, JSONL, Markdown, VTT, mbox) or, with encoding base64, an Excel workbook (.xlsx, up to 20 sheets and 50,000 rows per sheet, each sheet a CSV) or a PDF (its text layer, first 100 pages; a scanned PDF is listed as unreadable). Images, audio, video and archives are refused. Up to 100 files and 5 MB per call, 2 MB per file; call again with the returned upload_id to add more (300 files / 80 MB per upload); an upload not built within 24 hours is deleted. If you cannot read a system directly, ask your human to export into one shared folder, one subfolder per system; too large to pass through you, your human uploads the folder on Data sources › Scans. Needs: a key with upload consent.
