Florida Tax Certificate API
Florida Tax Lien API for Certificate Investors
Florida Tax Certs tracks Florida tax certificate sales, delinquent parcels, lands available, redemptions, certificate holders, and tax deed applications across all 67 counties. Coverage starts with the official county sale directory and expands into certificate-level data through public vendor portals, county downloads, CSV imports, and public-record sources — so you can screen tax liens by county, status, face amount, and interest rate without juggling LienHub, RealAuction, and TaxCertSale logins.
