ContactOut People Enrich (Multi-Signal)

Use this endpoint when you have multiple partial identifiers for a person (e.g. name + company, or email + LinkedIn) and want to resolve and enrich their full contact profile. Prefer this over the single-signal endpoints (email-only or LinkedIn-only enrich) when you have mixed or overlapping signals that together improve match accuracy. Best for CRM enrichment, sales prospecting, and recruiting workflows where you need comprehensive contact and professional data.
