Your Merchant ID is an 18-digit number starting with '14', provided by LianLian Pay after your account is successfully registered and verified. You can find it in the LianLian Global portal dashboard.

How do I set up the RSA keys for API calls?

Generate a 2048-bit RSA key pair. Upload your Public Key to the LianLian Global portal under [Developer Settings]. Use your Private Key in the credentials section of this server to sign requests.

Can I initiate a refund through the agent?

LianLian Pay + Pydantic AI FAQ

Common questions about integrating LianLian Pay 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 LianLian Pay MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
