Developer API
Property data & source-matched contacts, on demand.
Search 150M+ U.S. property records for free, then pull the owner's source-matched phone & email data for exactly the records you want — as JSON or CSV. You only pay per record you take. For normal list builds, account-level dedup skips records that account already pulled; enrichment follows its separate match-and-settlement rules.
What you can do
Everything from finding leads to pulling verified contacts.
Search 150M+ records — free
Filter the verified 153.9M-record July 2026 inventory by 60+ criteria and get instant counts plus summaries. No credits to search or preview.
Phone-matched contacts
Pull owner wireless, landline, CLEC-classified numbers, and email for the properties you choose. CLEC is reported separately and does not prove mobile or connected status. Source DNC signals and match-quality scoring are included.
Preview before you pay
See exactly how many records match and the credit cost, before spending a single credit.
JSON or CSV
Take the data as structured JSON for your app, or download a ready-to-use CSV for your CRM, dialer, or team.
List-build dedup
For normal list builds, records the same account already pulled are skipped and not charged again. Address enrichment follows its separate match-and-settlement contract.
Built for automation
Clean REST, API keys, rate limits, safe retries. Drop-in for any language, no-code tool, or AI agent.
