CSV & JSON export
The full 50-state rate table — sale type, statutory rate, redemption period, and full write-up for every state — free, no account, no API key. This is state-level statutory data, not individual parcel listings; for real, dated county auctions see Market Pulse.
states.csv
Opens straight in Excel, Google Sheets, or Numbers.
Downloadstates.json
Structured JSON, for scripts, spreadsheet formulas, or your own tool.
Quick example
curl https://taxlien.io/states.json | jq '.[] | select(.usps=="FL")'Both endpoints are open — no auth, no rate limit, CORS enabled so you can fetch them straight from a browser-based tool. Fields: slug, usps, name, summary, type, rate, redemption, blurb.
Data is informational, not financial or legal advice, and updates whenever the underlying state page does — no versioning or changelog yet, so if you're building something that depends on stability, cache your own copy rather than hitting this live on every request.
