Support & Guidance

Frequently Asked Questions

01

What are the benefits of using Lead APIs?

Using APIs for sales intelligence allows you to automate repetitive tasks, ensure data consistency across your stack, and enable AI agents like Claude to perform actions on your behalf without manual data entry.
02

How do I ensure high data accuracy with enrichment APIs?

The best practice is to use a 'Waterfall' approach—if the first API doesn't have a result, your script automatically queries a second or third provider. This ensures you get verified emails and phone numbers nearly 100% of the time.
03

How do I connect these tools to Claude Code or agentic tools?

Most tools listed here have official MCP servers or well-documented REST APIs. You can simply provide the API documentation link to your agent and ask it to write an integration script or perform a specific task using that tool.
