- –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
- +API access included on the permanent Free plan
- +Published OpenAPI JSON and per-endpoint rate limits
- +Test API key for Domain Search, Email Finder and Email Verifier
- –No official SDKs found, community wrappers only
- –Narrow scope: strongest on work emails, weak on phones and non-public contacts
- –Free tier is only 50 credits/month
