PUT https://api.getzep.com/api/v4/agents/{agent_uuid}/literal-policy
Content-Type: application/json

Reference: https://docs-beta.getzep.com/sdk-reference/agent/literal-policy/update

## Authentication

## Request

### Path parameters

- `agent_uuid` (string, required) — Agent UUID

### Body (application/json)

This endpoint expects a v4.UpdateAgentLiteralPolicyRequest.

- `allowlisted_classes` (v4.AgentLiteralPolicyClasses, required) — Typed reusable literal classes.
- `allowlisted_values` (v4.AgentLiteralPolicyValues, required) — Exact reusable values scoped by tools and environments.
- `default` (enum, required) — The remediation for literals that are not explicitly allowed.
  - Allowed values: `parameterize`, `remove`, `reject`
- `expected_revision` (integer, optional) — The current literal-policy revision used for optimistic concurrency.

## Response

### 200

OK

- `allowlisted_classes` (v4.AgentLiteralPolicyClasses, optional) — Typed classes that the policy may preserve.
- `allowlisted_values` (v4.AgentLiteralPolicyValues, optional) — Exact reusable values that the policy may preserve when applicability matches.
- `created_at` (string, optional) — The time this explicit revision was created. Omitted for revision zero.
- `created_by_principal_id` (string, optional) — The principal identifier that created this explicit revision. Empty for revision zero.
- `created_by_principal_type` (string, optional) — The principal type that created this explicit revision. Empty for revision zero.
- `default` (string, optional) — The remediation for literals that are not explicitly allowed.
- `digest` (string, optional) — SHA-256 of the canonical policy JSON.
