Perplexity

Type-safe tool execution

Every response from the server gets validated against Pydantic models. You catch bad data before it hits your logic. If the API returns a malformed response, the agent fails immediately. You get total predictability.

Strict annotation management

Use `update_annotation` with confidence. The framework ensures the payload matches the expected schema every time. No silent errors here. Your agent confirms the update succeeded or throws a validation error.

Access song data with schemas

When you call `get_song`, the server data is cast into a clean model. You always know exactly what fields you have. This makes development faster. You stop guessing what the API might return and start building.
