Nyne.ai API Documentation

The intelligence platform for people and company data. Build contact discovery, data enrichment, and social graph analysis into your products with our APIs.

For AI Agents

Unauthenticated agents usually find the HTML docs first, so the machine-readable entry points are linked here explicitly. Start with llms.txt, then load the agent manifest, then switch to page-specific markdown by appending .md to any endpoint documentation path.

Recommended Start Order Read llms.txt for the index, use the manifest to choose the right endpoint, then load the endpoint's .md doc before generating code. The HTML pages are useful for humans, but the markdown pages are cleaner for agents.
MCP Coverage Note The hosted MCP quickstart covers the common person search, person enrichment, and profile-Q&A workflows. The HTTP API surface is broader, so agents that need full endpoint coverage should follow the manifest and markdown docs first.
Task Recommended API Use When
Known person from email, phone, or LinkedIn URL Person Enrichment You already know the person and need structured identity, work history, and contact data.
Recent messaging context for a known person Person Newsfeed You need recent posts, topical context, and language cues for outreach.
Direct question answering about a known person Person Ask You want the platform to answer a focused question instead of composing custom logic client-side.
Full prospect brief or dossier Deep Research You can afford higher cost and latency for a richer all-in-one report.
Natural-language contact search Person Search You want people who match an ICP or description and need contact-enriched results.
Keyword plus location people discovery Person Discover You want keyword-based discovery rather than a freeform natural-language search.
Open-web discovery with requirements and citations Discovery API You need requirement matching, source citations, and optional extracted fields from open-web discovery.
Social-post-driven lead generation Person Leads You want leads sourced from people actively posting about relevant topics.
Known company from a name, domain, or company social media URL Company Enrichment You already have a durable company identifier and need firmographics or profile data.
Public employee profiles for a known company Company Employees You want a structured list of public people profiles associated with a known company identifier like a name, domain, or company social media URL.
Company challenges from filings Company Needs You want business pain points or challenge summaries from public filings.
