Steps
Search the Miami-Dade Open Data Hub (opendata.miamidade.gov or gis-mdc.opendata.arcgis.com) for property appraiser datasets such as Property Point View
Use the dataset's ArcGIS REST API endpoint to query by folio number, address, or spatial extent
Parse returned fields for assessed/market value, land use, and ownership as published by the Property Appraiser
For data needs beyond what the open data layer exposes, submit a bulk data file request to the Property Appraiser's data request contact instead of scraping
Reconcile folio numbers against any existing parcel identifiers (e.g., Regrid or ATTOM parcel IDs) since Miami-Dade uses its own folio numbering scheme
Known gotchas
The richest appraiser fields are distributed as downloadable bulk files (via a data request), not fully exposed through the open data API layer — plan for a hybrid API-plus-bulk-file approach for complete coverage
Miami-Dade's folio number format is specific to the county and will not directly match parcel ID formats used by other counties or by nationwide parcel vendors
Open data layers are refreshed on the county's own schedule and can lag the authoritative Property Appraiser system after assessment updates or ownership changes
