Strengths and weaknesses
- +Documented REST API with search, lookup, bulk jobs, webhooks and email verification
- +Public status page covering API, MCP and Verify components
- +Official MCP server and Claude Code setup guide
- –Free plan is 5 lookups per month and excludes API access
- –API reportedly requires the Ultimate plan (about $2,099/year) or custom Team plans
- –Trustpilot about 1.2/5 from 1,000+ reviews, dominated by billing, auto-renewal and cancellation complaints
- +Deepest enterprise B2B database among enrichment APIs: ~321M+ contacts across 104M+ companies with strong direct-dial and mobile phone coverage
- +Excellent accuracy and coverage for US/North American enterprise contacts (VP+ at 200+ employee firms)
- +Asynchronous Scaling APIs with webhook callbacks handle large batch enrichment jobs cleanly
- –Opaque, sales-gated pricing with five-figure annual minimums (~$50K/year for the full API)
- –Coverage and accuracy drop sharply outside the US/Canada
- –Data freshness is cycle-based (~90-day validation refresh), not real-time, leading to email bounces in cold outreach
