FAQ

Frequently asked questions

01

How do I find my FindThatLead API Key?

Log in to your FindThatLead account, navigate to Settings > API Access, and copy your unique token.

02

Does email verification consume credits?

Yes, each successful email verification or lead search typically consumes one credit from your FindThatLead account balance.

03

Can I search for local businesses by city?

Absolutely. Use the local_prospector tool and provide a keyword (e.g., 'Dentist') and a location to find businesses in that area.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
