# Experiment Fields

`GET /api/v1/agents/{agent_id}/experiments/fields`

What this agent's builder may offer, from the server's own allow list.

The UI reads its option set from here rather than hardcoding one, so a field can
never appear in the builder that the API would refuse on save.

## Path parameters

- `agent_id` string, uuid, required

## Headers

- `authorization` string, nullable — Bearer <token>

## Response `200`
