Sixtyfour AI — People & Company Intelligence

Description

--- name: sixtyfour description: "People and company intelligence via the Sixtyfour AI API. AI research agents that read the live web — not static databases — to return structured, confidence-scored profiles. Use when you need to: (1) enrich a lead with full profile data (name, title, email, phone, LinkedIn, tech stack, funding, pain points — up to 50 custom fields), (2) research a company (team size, tech stack, funding rounds, hiring signals, key people), (3) find someone's professional or personal email address, (4) find phone numbers, (5) score/qualify leads against custom criteria with reasoning, (6) search for people or companies via natural language query, or (7) run batch enrichment workflows via API. NOT for: general web browsing, tasks unrelated to people/company data, or non-enrichment research." --- # Sixtyfour AI — People & Company Intelligence AI research agents that investigate people and companies across the live web, returning structured, confidence-scored data. 93% accuracy — benchmarked against Clay (66%), Apollo (72%), and ZoomInfo. **Base URL:** `https://api.sixtyfour.ai` **Auth header:** `x-api-key: YOUR_API_KEY` (all requests) **Free tier:** 50 deep researches on signup — [app.sixtyfour.ai](https://app.sixtyfour.ai) (Google sign-in, API key available immediately) **Docs:** [docs.sixtyfour.ai](https://docs.sixtyfour.ai) **OpenAPI spec:** [api.sixtyfour.ai/openapi.json](https://api.sixtyfour.ai/openapi.json) ## Setup ```bash # 1.
