Type-safe document management for Pydantic AI

Your agent validates every response from `list_esign_documents` against Pydantic models. This ensures the data your agent processes is always structured correctly. It pulls document status using `get_document_detailed_data` to verify the exact state of your contracts. Any unexpected API field causes an immediate validation failure.

Strict audit tracking in Pydantic AI

Your agent retrieves audit logs via `list_document_audit_trail` with full type enforcement. This ensures your compliance checks are based on reliable, validated data. Use `quick_signing_volume_audit` to monitor your document activity. The agent treats this summary as a typed model for reliable analytics.

Template validation for Pydantic AI

Your agent uses `list_esign_templates` to fetch available documents. It confirms template parameters through `get_template_details` before proceeding with any action. This approach removes guesswork from your automation. Your agent checks account limits via `get_esignly_account_metadata` to ensure your workflow stays within your service tier.
