Florida Tax Certificate API
Florida Tax Certificate API — Sales, Holders & Redemptions
Florida Tax Certs is a statewide tax-certificate intelligence layer that normalizes fragmented public county and vendor data into search, API, CSV, alerts, and parcel-linked investor workflows. Query certificates by county, parcel, tax year, or status with structured JSON envelopes — coverage starts with the 67-county sale directory and grows into certificate-level records vendor-by-vendor as each county tax collector's publication is wired in.
