Person Entity Resolution API

AI-powered digital identity resolution across social platforms

Available at: https://entity-resolution-demo.parallel.ai

What It Does

This API finds all social media profiles belonging to a single person. Give it a name, email, username, or any profile URL—it returns verified matches across Twitter, LinkedIn, GitHub, Instagram, Facebook, TikTok, and more.

The problem: People fragment their presence across dozens of platforms. Traditional search can't reliably connect these scattered identities.

The solution: AI-powered entity resolution that finds and verifies profiles through cross-referencing and confidence scoring.

Why It Matters

For Sales & Revenue

• Richer prospect intelligence: Find prospects' GitHub repos, technical blogs, conference talks beyond LinkedIn
• Better qualification: A CTO active on GitHub is different from one who isn't
• Warmer introductions: Discover mutual connections across any platform

For Recruiting

• Complete candidate profiles: Evaluate technical skills (GitHub), communication (Twitter), thought leadership (blogs)
• Passive sourcing: Find engineers active on GitHub but not updating LinkedIn
• Cultural fit: See how candidates present themselves across contexts

For Customer Success

• Relationship intelligence: Identify vocal advocates and at-risk customers
• Multi-channel engagement: Meet champions where they are
• Expansion signals: Track when decision-makers change roles

For Data Quality

• CRM deduplication: Merge duplicate records by linking profiles to single entities
• Enrichment at scale: Turn sparse contact data into rich profiles
• Attribution accuracy: Know which database profiles are the same person

How It Works

1. Submit a person identifier (name, email, username, or profile URL)
2. AI searches across major platforms and verifies matches
3. Returns structured profile data with confidence indicators

Built using Parallel's Task API and OAuth Provider.

Quick Start

// Submit resolution request
const response = await fetch("https://your-api.com/resolve", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "x-api-key": "your-api-key",
  },
  body: JSON.stringify({
    input: "john.doe@techcorp.com or @johndoe on Twitter",
  }),
});

const { trun_id } = await response.json();

// Poll for results
const result = await fetch(`https://your-api.com/resolve/${trun_id}`, {
  headers: { "x-api-key": "your-api-key" },
});

const { profiles } = await result.json();

Example Response

{
  "profiles": [
    {
      "platform_slug": "twitter",
      "profile_url": "https://twitter.com/johndoe",
      "is_self_proclaimed": true,
      "is_self_referring": true,
      "match_reasoning": "Profile bio links to LinkedIn and GitHub profiles found in search",
      "profile_snippet": "CTO @TechCorp | Building AI infrastructure | Thoughts on ML systems"
    },
    {
      "platform_slug": "github",
      "profile_url": "https://github.com/johndoe",
      "is_self_proclaimed": true,
      "is_self_referring": false,
      "match_reasoning": "Linked from Twitter profile, same name and company affiliation",
      "profile_snippet": "CTO at TechCorp. 50 repositories, 2.3k followers"
    }
  ]
}

Field Explanations

is_self_proclaimed: Profile was discovered through the person's own references. Either directly mentioned in input, linked from a mentioned profile, or linked transitively. High confidence indicator.

is_self_referring: Profile links back to other profiles in the result set. Bidirectional verification increases confidence.

match_reasoning: Human-readable explanation of why the AI matched this profile. Use for quality assurance and debugging.
