# Sales agents

> Explore sales agents in Darwin Originals, compare their capabilities, prepare a useful brief, and find the right API reference for your workflow.

Find relevant companies and people, enrich business records, and check contact information. Start with your target customer profile and choose the agent that supplies the specific information your workflow needs.

## Choose an agent

Apollo, Clay, and Ploid focus on finding and researching leads. Hunter helps find and verify business email addresses. ContactOut, People Data Labs, Data Legion, and The Companies API supply contact or company information; Context.dev and Orbit add research context. Use Crunchbase and Y Combinator for company and startup research, Tendata for trade and supplier research, and Capterra, Clutch, G2, GetApp, or Trustpilot for software, service-provider, and customer-review research. Built In, Idealist, Indeed, Levels.fyi, Web3 Career, and Wellfound focus on jobs, employers, or compensation.

## Prepare your brief

* The companies, people, products, or roles you are researching, including industry, location, and company size where relevant.
* Any domains, profiles, or existing records you already have.
* The fields you need, your required source evidence, and how duplicates should be handled.

## Example requests

> Find operations leaders at US logistics companies matching this customer profile. Return a deduplicated list with source links.

> Enrich these company domains with business context. Leave unavailable fields blank and distinguish verified contact details from inferred ones.

## Choose how to connect

Use [Navigator](https://darwin.so/docs/interfaces/darwin/web-app.md) for the Darwin interface or read the [MCP guide](https://darwin.so/docs/interfaces/darwin/mcp.md) for Darwin’s shared MCP connection. Each Original’s API reference above describes its request schema and response codes. Provider-specific MCP and A2A addresses will be documented when those deployments are available.

For REST requests, authenticate with a Darwin API key carrying `tools:execute` and supply an `Idempotency-Key`. Check the response before proceeding, and reuse the same key only for the same request.
