Retrieve the list of conditionally required or applicable fields for creating a counterparty together with their constraints.

:::note [Note] This feature is not available in Sandbox. :::

When creating a counterparty via the Create a counterparty endpoint, certain fields (such as first_name, last_name, company_name, tax_id, route, or account_type) become required depending on the counterparty's bank country, currency, and profile type. This read-only endpoint allows you to discover these contextual fields dynamically, along with their validation rules and available options.

Only the fields relevant to the specific context are returned. The input parameters (country, currency, and recipient_type) are intentionally excluded from the response.

For more details, see the guide: Check counterparty field requirements section in Create a counterparty.
