Admin-only endpoint. Your user role={user_api_key_dict.user_

Error message

Admin-only endpoint. Your user role={user_api_key_dict.user_role}

What it means

GET /customer/list is restricted to PROXY_ADMIN and PROXY_ADMIN_VIEW_ONLY roles taken from the authenticated key's user (user_api_key_dict.user_role). Any other role (internal_user, team member, etc.) gets HTTP 401 with the caller's actual role echoed in the message. Note the DB check on this route comes after the role check.

Solutions

Call with the master key (LITELLM_MASTER_KEY) or a key whose user has the proxy_admin role
An admin can elevate the user via /user/update (role: proxy_admin), or issue a proxy_admin_view_only key for read-only access
Non-admin callers should use scoped endpoints (e.g. GET /customer/info) instead of the full listing

Example fix

# before
headers = {"Authorization": "Bearer sk-team-key"}   # internal_user role -> 401

# after
headers = {"Authorization": "Bearer sk-master-key"}    # proxy_admin -> 200

Defensive patterns

Strategy: validation

Validate before calling

import httpx


def is_admin_key(base: str, headers: dict) -> bool:
    key = headers["Authorization"].split(" ", 1)[1]
    info = httpx.get(f"{base}/key/info", params={"key": key}, headers=headers).json()
    role = (info.get("key_info") or {}).get("user_role")
    return role in ("proxy_admin", "proxy_admin_view_only")

Try / catch

try:
    r = httpx.get(f"{base}/customer/list", headers=headers)
except httpx.HTTPStatusError as e:
    if e.response.status_code == 401 and "Admin-only endpoint" in e.response.text:
        raise PermissionError("/customer/list needs a proxy_admin key") from e
    raise

Prevention

Store admin and non-admin keys separately in secret managers and label them clearly
Check the key's user_role via /key/info before scripting admin endpoints
Grant proxy_admin_view_only for reporting tooling that only needs to read

When it happens

Trigger: Calling GET /customer/list with a virtual key whose owning user is not a proxy admin - team-scoped keys, personal keys, or org-member keys created via /user/new.

Common situations: Operators holding team keys try to enumerate all customers; scripts pull the wrong secret from a vault; new staff have the default internal_user role and attempt admin operations on day one.
