Alternative to LienHub & RealAuction — Florida Tax Certificate API
Florida Tax Certs is a developer-first alternative for accessing Florida tax certificate and delinquent-tax records. Instead of juggling logins across LienHub, RealAuction, TaxCertSale, WFBS, and Pacific Blue, Florida Tax Certs normalizes the fragmented public county and vendor data into one REST API, CSV exports, alerts, and a public web search funnel — covering certificate sales, holders, redemptions, lands available, and the tax deed pipeline across all 67 counties. Coverage starts with the official county sale directory and expands into certificate-level data vendor-by-vendor.
