Yes, there are limitations for the free account:
1. You get 1.2K credits per year (or 100 credits per month) for enrichments.
2. For LinkedIn prospecting specifically, searches are capped at 5,000 results per search.
3. Phone number enrichments are not available on the free plan.
It's worth noting that you only pay credits for actual data enrichment - prospecting from sources like companies, Google Maps, GitHub, CRM tools, and web scraping is free.
Any unused credits can roll over, but they're capped at twice your monthly credit limit.
