The people data API for AI agents.
Nyne.ai is a real-time people data API: hand it a fragment, a hashed email, a half-filled CRM row, a name and a city, and identity resolution matches it into a graph of over two billion people. Person enrichment returns the whole record: demographics, household, wealth, affinities and live life-event signals, every field scored, sourced and time-stamped.
What happens in 184 milliseconds.
Every request walks the same road: identity resolution, data enrichment, live signals, delivery. Scroll a record through it.
Identity resolution
Three half-records walk in, one person walks out. Duplicate contacts, aliases, old addresses and typos are matched against the identity graph, deduplicated and merged into a single resolved profile with a match confidence score.
Person enrichment
From six fields to 2,400+ attributes. Contact enrichment and consumer data complete the record: demographics, household composition, income and wealth, residence and property, affinities, career and company.
Life-event signals
The record stays alive after you fetch it. Home purchases, new movers, job changes and wealth events land on the profile as they happen and stream into your CRM, CDP or agent workflow by webhook.
Agent-ready delivery
The whole person in one JSON payload: typed fields with confidence scores, sources and freshness timestamps, returned by a real-time REST API in 184ms at the median.
Four doors into one identity graph.
People search, person enrichment, company enrichment and audience building, all reading from the same verified graph of two billion people.

Context your AI can act on.
One call returns the structured person: typed fields, confidence scores, provenance and freshness. Connect over REST, webhooks or the MCP server, so AI agents can query the graph as a native tool in agentic workflows. It works both ways: Nyne.ai's own autonomous AI agents continuously source and verify the data underneath.

Common questions.
What is a people data API?
A people data API returns structured information about a person or household from an identifier such as an email, name or address. Nyne.ai's people data API resolves the identifier against a graph of over two billion people and returns verified attributes with confidence scores, sources and timestamps.
What data does Nyne.ai's enrichment API return?
Demographics, residence, income and wealth, affinities, life events, state, county and national filings, contact, social and career and company data. Every field carries a confidence score, source and freshness timestamp.
How does Nyne.ai source its data?
Nyne.ai's autonomous AI agents continuously source and verify data across the open web and public records, including state, county and national filings. Records are matched into the graph, deduplicated, scored and time-stamped.
Can AI agents use Nyne.ai?
Yes. Nyne.ai is built for AI agents: one API call returns the structured person as typed JSON an agent can act on, and webhooks push life events into CRMs, CDPs and agent workflows in real time.
Does Nyne.ai cover consumers as well as professionals?
Both. Nyne.ai covers consumer and household attributes such as demographics, wealth and affinities alongside professional context such as roles, companies and job changes, in one unified graph.
Is Nyne.ai privacy compliant?
Nyne.ai is CCPA-ready: every field is sourced, opt-outs are honored, there are no shadow profiles and records are point-in-time auditable.
Does Nyne.ai offer an MCP server for AI agents?
Yes. Nyne.ai ships a Model Context Protocol (MCP) server, so AI agents and assistants can call people search, person enrichment and company enrichment as native tools inside agentic workflows. REST endpoints and webhooks are available alongside it.
How much does the people data API cost?
Pricing is usage-based: each API call consumes credits, and every new account starts with free sandbox credits so you can evaluate real responses before paying. Current per-call credit costs are listed in the documentation.
What can I build with a people data API?
Typical uses include CRM and contact enrichment, lead generation and sales intelligence, consumer audience segmentation, identity verification and fraud checks, personalization, and giving AI agents verified human context. One graph powers both consumer and professional use cases.
How is Nyne.ai different from other people data providers?
Nyne.ai unifies consumer and professional data in one identity graph, adds live life-event signals, and returns every attribute with a confidence score, source and freshness timestamp. It is built API-first for AI agents, with structured JSON, webhooks and an MCP server.
