Strengths and weaknesses
- +Multi-field enrichment: accepts many identifier types (email, phone, name+address, social URLs/usernames, MAIDs, plus Resolve PersonIDs) to lift match rates

- –Data-quality complaints of false positives in age, employment, and education fields, with no data-freshness timestamps on attributes
- –Rate limit (~600 queries/min) too low for large batch enrichment jobs
- +Waterfall across 20+ providers with success-based billing
- +Webhook delivery recommended, plus polling for results
- +v1 and v2 OpenAPI specs and an llms.txt docs index
- –No official SDKs found
- –Mobile reveals cost 10 credits and personal emails 3
- –Enrichment-only: no signals, outreach or native CRM breadth
