How do I trigger an automated credit decision?

Use the `submit_loan_application` tool with the unique application ID. This will trigger the rules-based or AI-driven decision engine configured in your LendAPI account.

Can I search for valid values for specific fields like 'purpose'?

Yes, the `get_lendapi_picklists` tool allows you to retrieve the full list of allowed values for various metadata fields, ensuring your application data is compliant.

Is it possible to manage borrower profiles via the agent?

Absolutely. You can list all borrowers, retrieve detailed profile information, and create new borrower records using the specific borrower tools provided.
