# List extraction fields

> List the details an agent pulls out of each conversation.

> [!NOTE]
>
> This endpoint is for the VIP plan only. Other plans get a `403`. See [Plan access](https://docs.nedzo.ai/api-reference/introduction.md#plan-access).

After each conversation, the agent fills in its extraction fields. They show in the conversation log and in the post-conversation webhook, and each one saves its value to a custom field on the contact. First name, last name, email, phone and company are filled in on their own, so they need no field.
