Example prompt: I just uploaded a CSV file to my MiniUp app (site ID abc123) — can you convert it into a parquet-backed API dataset so I can query it through MiniUp?

## When to prefer this

Use this endpoint after uploading a data file (CSV, XLSX, JSON, GeoJSON, Shapefile ZIP, Parquet, or GeoParquet) to a MiniUp app and needing to convert it into a queryable, parquet-backed API dataset. This is the dedicated conversion step in the MiniUp data pipeline, following the presigned URL upload and multipart completion steps.

## Known failure modes

- Invalid or missing siteId returns 404 not found
- File not yet uploaded or upload not completed returns 400 bad request
- Unsupported file format returns 422 unprocessable entity
- Payment not provided or insufficient USDC balance returns 402 payment required
- File is corrupt or malformed returns 500 or 422 error
- Conversion timeout for very large files
