Type-safe Mercado Livre Interactions for Pydantic AI

Every response from `get_reputation` or `get_metrics` is checked against Pydantic models. You get clean, validated data every time. If the marketplace returns a malformed response, the agent flags it immediately. You avoid the headache of dealing with unexpected data structures.

Execute precise actions in Pydantic AI

Use `answer_question` to send replies that match your strict type definitions. Your agent ensures every payload is formatted correctly before it hits the API. This prevents silent failures or bad data from reaching your buyers. You maintain total control over what your agent sends.

Organize buyer inquiries using Pydantic AI

Use `get_questions` to fetch pending items and `get_messages` to pull conversation threads. Your agent parses these into structured objects. You gain a clear view of your customer service queue. Your agent handles the details while you focus on the exceptions that need human eyes.
