Search. Verify.
Refund. Export.
Every LeadsApp account includes these free: search 136M+ US and Canada B2B contacts, verify any email address, and call both over REST or MCP from your own AI agents. This is where LeadsApp started, and it stays free.
Free, unlimited search across 136M+ contacts
Filter by industry, role, country, state/region, company size, and full-text. Fast, indexed queries return results instantly. Search is FREE — you only spend credits on verify + reveal.
- ›6 filter dimensions: industry, role, country, region, size, full-text
- ›Free + unlimited searches (no credit cost)
- ›Rate-limited to prevent abuse, not throttled for paid users
- ›Index currently 136M+ contacts (US + Canada), verified on reveal
Domain + typo verification at reveal
Every email checked the moment you reveal it: MX records verified, common typos corrected (gmail.con → gmail.com), disposable providers blocked, role addresses flagged. Cached 30 days, re-verified at the next reveal.
- ›MX record lookup
- ›Disposable provider blocklist
- ›Common typo correction engine
- ›Role-account detection (info@, contact@, etc.)
Auto-refund on non-deliverable
Every reveal verifies each email and refunds credits for non-deliverable contacts immediately. Tracked in the credit ledger so every grant + spend + refund is visible. No support tickets, no negotiation.
- ›Immediate credit refund at reveal time
- ›Refund applies to every reveal verification check
- ›Credit ledger tracks every grant + spend + refund
- ›No support ticket — automatic at the API layer

Compliance-aware filtering
Built with US data-broker laws in mind. CA / TX / VT / OR resident contacts and EU IPs are blocked entirely — both at the network edge and inside every API endpoint. No data-broker registration burden for sales operators.
- ›CA / TX / VT / OR contacts blocked at ingest + API
- ›EU contacts and EU IPs blocked entirely (GDPR posture)
- ›Defense-in-depth: edge + API + DB-level filters
- ›No registration burden under CA SB-362, TX HB-4, VT 9 V.S.A. §2446, OR HB 2052
