Developer Portal — available on the Developer plan ($349/mo) and above

Everything below is a working sample of the product — the same ledger, filled with placeholder filings, so you can see exactly what it does before you subscribe. Every figure on a live page is traced to its published source; the specimens here are not real records. Subscribing turns this into the live ledger: real county filings, working filters, and monitoring alerts on any scope.

  • Signed webhook delivery for change events.
  • An OpenAPI specification and an interactive reference.
  • Keys are tied to your account and honoured only while your tier is live.
