How do I obtain a HealthCare.gov API Key?

You must request a free API key through the **CMS Marketplace API** portal (developer.cms.gov/marketplace-api). Keys are typically sent via email and must be renewed every 60 days.

Can I check if my doctor is in-network for a specific plan?

Yes! Use the `get_provider_coverage` tool by providing the plan ID and the provider ID. The agent will confirm the network status for that specific combination.

What geographic information is required for plan searches?

Most searches require a 5-digit ZIP code and a 5-digit County FIPS code. You can use the `get_counties_by_zip` tool to retrieve the FIPS code for any ZIP code.

Is the integration secure for searching health data?

Absolutely. The integration uses official CMS API keys over HTTPS. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.

HealthCare.gov + Pydantic AI FAQ

Common questions about integrating HealthCare.gov MCP Server with Pydantic AI.

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 HealthCare.gov MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
