Frequently asked questions
How do I find my FindThatLead API Key?
Log in to your FindThatLead account, navigate to Settings > API Access, and copy your unique token.
Does email verification consume credits?
Yes, each successful email verification or lead search typically consumes one credit from your FindThatLead account balance.
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.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your FindThatLead MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
