Introduction

The Swarm API gives developers, AI agents, and product teams access to over 500 million professional profiles, 50 million companies, and the deepest relationship mapping data available on the market. Unlike traditional enrichment providers, The Swarm combines people data, company data, relationship intelligence, job changes, and fundraising data into a single platform accessible through APIs, integrations (including Clay, HubSpot, and others), and our native MCP server. The Swarm API is designed using the REST architectural style, employing standard HTTP methods for communication. Responses from the API are formatted in JSON (JavaScript Object Notation), a lightweight data-interchange format widely supported across various programming languages and platforms. This design choice ensures simplicity, flexibility, and ease of integration for developers utilizing the API.

​

MCP-native by design

The Swarm provides a native Model Context Protocol (MCP) server, allowing MCP-compatible tools to access live Swarm data directly. With MCP you can:

• Discover warm introduction paths
• Search people and companies
• Analyze professional networks
• Research accounts and prospects
• Build relationship-aware workflows

Relationships

The Swarm is built around relationship data. Create a team at app.theswarm.com to configure your “Connectors” (who you ask intros to) and we’ll passively map:

• Shared work experience
• Shared education
• Shared investors

Your users can then layer in LinkedIn connections and email/calendar contacts.

​

Network Mapper (for partners)

The Swarm pioneered the first Network Mapper API, enabling developers to programmatically discover warm introduction paths to target accounts and individuals. Used by Clarify, Clay, Unify, and many others already. Common use cases include:

• Building a relationship layer in your own product
• Mapping a new company network in minutes
• Helping users find intro paths into target companies
• Ranking introduction paths
• Building network-aware AI agents

​

Additional signals

The Swarm also provides under one umbrella:

• Job changes and career movement
• Funding and investor data
• Social engagement signals
• Real-time enrichment for people and companies

​

Built for modern applications

The Swarm powers growth teams for internal use cases as well as product teams at sales intelligence platforms, recruiting tools, VC workflows, AI agents, CRMs, and other agentic systems. The Swarm provides the data infrastructure needed to understand people, companies, and the connections between them.
