# Get a NetworkPolicy.

`GET /v1/network-policies/{id}`

Get a specific NetworkPolicy by its unique identifier.

## Path parameters

- `id` string, required

## Response `200`

Successfully retrieved the NetworkPolicy.

- NetworkPolicyView — A NetworkPolicy defines egress network access rules for devboxes. Policies can be applied to blueprints, devboxes, and snapshot resumes.
  - `id` string, required — The unique identifier of the NetworkPolicy.
  - `name` string, required — The human-readable name of the NetworkPolicy. Unique per account.
  - `description` string, nullable — Optional description of the NetworkPolicy.
  - `egress` EgressRulesView, required — Egress (outbound) network rules for a NetworkPolicy.
    - `allow_all` boolean, required — If true, all egress traffic is allowed and other fields are ignored. Used for ALLOW_ALL policies.
    - `allow_devbox_to_devbox` boolean, required — If true, allows traffic between the account's own devboxes via tunnels.
    - `allowed_hostnames` string[], required — DNS-based allow list with wildcard support. Examples: ['github.com', '*.npmjs.org', 'api.openai.com']. Empty list with allow_all=false means no network access (DENY_ALL behavior).
    - `allowed_cidrs` AllowedCidr[], required — CIDR-based allow list with optional port restrictions, additive with allowed_hostnames.
      - `cidr` string, required — IPv4 CIDR block in canonical form (host bits zero), e.g. '10.12.0.0/16'.
      - `ports` PortRule[], nullable — (Optional) Ports allowed for this CIDR. Empty or omitted means all ports and protocols.
        - `port` integer, required — The allowed port (1-65535), or the start of a port range.
        - `end_port` integer, nullable — (Optional) Inclusive end of the port range (port-65535). Omit for a single port.
        - `protocol` 'TCP' | 'UDP' — L4 protocol for a port rule.
    - `allow_agent_gateway` boolean, required — If true, allows devbox egress to the agent gateway for credential proxying.
    - `allow_mcp_gateway` boolean, required — If true, allows devbox egress to the MCP hub for MCP server access.
    - `allow_runloop_mirrors` boolean, required — If true, allows devbox egress to Runloop's package/image registry mirrors. Implicitly allowed when allow_all is true.
  - `create_time_ms` integer, required — The creation time of the NetworkPolicy (Unix timestamp in milliseconds).
  - `update_time_ms` integer, required — Last update time of the NetworkPolicy (Unix timestamp in milliseconds).

## Other responses

- `401` — Unauthorized. Invalid or missing authentication.
- `403` — Forbidden. Account does not have devbox capability.
- `404` — NetworkPolicy not found.
- `500` — Internal server error.
