Perplexity

Type-safe search for Pydantic AI

Use `search_datasets` to retrieve catalog information. Because your agent is built on Pydantic, the results are validated against your expected response models immediately. This ensures your agent works with clean data identifiers. If the search returns an unexpected format, your agent catches the validation error instantly.

Structural validation for Pydantic AI

Call `get_dataset_metadata` to verify dimensions and code lists. Pydantic AI checks the structure of the metadata before the agent proceeds to query the data. This eliminates silent failures. You define the expected schema, and the agent confirms the Eurostat response matches it before taking further action.

Strict data querying for Pydantic AI

Invoke `get_dataset` to bring statistical values into your agent. The response is validated against your Pydantic models, guaranteeing that the numbers you receive fit your application's requirements. It provides a reliable interface for your agent. You avoid issues with mismatched fields or unexpected data types common in raw API responses.
