Which Person API Should an Agent Use?
The most common mistake is picking the wrong person endpoint because several names overlap. Use this routing table before writing any integration code, and prefer the markdown docs for the specific endpoint once you pick it.
| Goal | Recommended API | Why |
|---|---|---|
| Enrich a known person from email, phone, or LinkedIn | Person Enrichment | Best starting point when you already know the person and want structured profile data. |
| See what they have posted recently | Person Newsfeed | Best for recency, tone, and topical context. |
| Validate whether a social profile or post is visible | Social Account Validator | Best when you need screenshot proof and a visibility classification for a public social target. |
| Ask a focused question about the person | Person Ask | Lets Nyne route the question internally instead of forcing the client to infer the right sub-system. |
| Get an explainable interest or psychographic layer | Person Interests | Use as a high-value optional layer, not your only source of personalization. |
| Search an ICP in natural language | Person Search | Best when your starting point is a natural-language description of who you want. |
| Find people from keyword plus location criteria | Person Discover | Best when you want keyword-driven discovery rather than a broader natural-language search. |
| Find people from the open web with requirements and citations | Discovery API | Best when you need source-backed matches and optional extracted fields. |
| Generate social-post-based leads | Person Leads | Best when recent posting behavior is the lead source. |
| Get a full multi-source prospect brief | Deep Research | Best all-in-one option when you can afford the higher cost and latency. |
