Person and Company Enrichment APIs

Person and Company Enrichment APIs

Person and company enrichment APIs allow organizations to append, clean, and verify customer and lead records in real time using automated tools and integrations. These platforms leverage diverse data sources, identity graphs, and webhooks to support sales, marketing, and outreach workflows.

Core Features and Data Capabilities

Enrichment platforms offer wide-ranging data attributes and scale. Clearbit Enrichment adds 100+ B2B data points on target accounts from a dataset distilled from 250+ sources, refreshing records automatically upon change [2]. FullContact appends over 900 unique attributes utilizing an identity graph covering 248 million profiles and 50 billion identifiers, processing 200 million daily updates with a 40ms response time and 99.99% uptime [4]. Abstract's Company Enrichment API supplies employee counts, locations, and industries across 170+ countries with weekly updates from public databases and LinkedIn [7].

People Data Labs provides Person and IP Enrichment APIs, where the Person API looks up profiles using names, locations, emails, phones, education, work, and social information, and the IP Enrichment API maps IPv4 or IPv6 addresses to companies [3]. Dropcontact operates without personal databases to ensure GDPR compliance, delivering 98% valid emails and over 85% for catch-all domains while enriching company data with SIREN numbers, NAF codes, and intra-community VAT numbers [6]. Proxycurl offered person profiles, contact details, salary ranges, company data, and job listings, though it is no longer in service and its founder directs users to NinjaPear [5].

Integrations and Workflows

Platform integrations vary across direct APIs, webhooks, and cloud automation tools. Abstract supports REST APIs, CSV uploads for bulk queries, and Zapier, Splunk, Snowflake, Shopify, Salesforce, Pipedream, Pardot, Openprice, NetSuite, Marketo, Make, Mailchimp, and others [7]. People Data Labs delivers data via direct APIs, data feeds, Snowflake, Databricks, AWS, and GCP, alongside Zapier and Make integration [3]. Dropcontact integrates natively with Pipedrive and HubSpot in under 5 minutes, connects to over 1,200 solutions through Zapier, Make, and n8n, and offers a Google Workspace extension for Google Sheets [6]. Clearbit uses powerful APIs and modern webhooks [2].

Linked API acts as a secure automation platform for LinkedIn that executes workflows on dedicated cloud browsers simulating natural user behavior, rather than using headless scripts like Puppeteer or Selenium [1]. It integrates with AI tools like Claude, Codex, ChatGPT, Cursor, Windsurf, and OpenClaw via MCP server or API calls to search companies, extract employees, filter positions, enrich profiles, and export to CRMs [1]. Sapiengraph functions as a Google Sheets addon granting Proxycurl capabilities to non-developers [5].

Pricing and Plans

Linked API offers Core and Plus plans starting at $49 per seat per month with a 7-day free trial and unlimited workflow execution; the Plus plan is $74 per seat per month [1]. Abstract provides a free tier with 100 requests, a standard plan at $99 per month, and custom enterprise options [7]. People Data Labs structures pricing per match, allowing users to define match strictness and required fields [3].

Exact rate limits and latency metrics for most individual API endpoints beyond FullContact's specified response time are omitted. Detailed enterprise custom pricing tiers for platforms like People Data Labs and FullContact are not provided.
