AI agents call apollo_enrich_person to retrieve information from Apollo Io without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or augments existing person data from Apollo.io's database to provide additional intelligence fields (likely contact info, company details, job titles, etc.). It has no side effects—it does not create, modify, delete, execute code, or commit financial actions. It is a straightforward data enrichment/retrieval operation typical of B2B sales intelligence platforms.
