Perplexity

Enforce schema safety in CloudLex Legal

Pydantic AI validates every response from `get_cloudlex_case` against your strict Python models. If the data structure changes, the agent stops immediately. This prevents bad data from hitting your firm's records. You get reliable, typed data every single time you query a case.

Search cases using Pydantic AI

Execute `search_cloudlex_cases` to find specific matters by keyword query. Your agent filters the return values to ensure only relevant records remain. Type-safe constraints keep your search results clean. You avoid handling malformed data that could break your downstream workflows.

Track liens and expenses in CloudLex Legal

Your agent extracts financial data using `list_cloudlex_liens` or `list_cloudlex_expenses`. Each item undergoes validation before it reaches your dashboard. You gain a clear picture of case financials without manual parsing. Pydantic AI catches errors before you ever see them.

Active Vinkius subscription with a valid endpoint token
