Validated price data for Pydantic AI

Call `get_bitcoin_price_usd` or other currency-specific tools to receive prices that match your Pydantic models. If the data format changes, your agent throws a validation error immediately. This stops bad data from corrupting your agent's memory. You gain total control over the structure of incoming price feeds.

Strict timing checks for Pydantic AI

Use `get_latest_update_time` to ensure your agent understands the age of the price data. The tool provides a timestamp that gets validated against your time-tracking schemas. It prevents your agent from making decisions based on old trade information. You force the agent to reject anything that doesn't meet your freshness criteria.

Type-checked currency lookups in Pydantic AI

Run `list_supported_currencies` to identify valid market codes for your queries. The response is validated against your schema, ensuring you only request supported currencies. Use `get_bitcoin_price_custom` to pull the data once the code is confirmed. It guarantees that your Pydantic AI agent only works with valid, typed input.
