pixie python API client always failed to validate the apikey

[everestplusteam]

Describe the bug I tried to connect self-hosted cloud with python API, and followed the instruction to generate apikey and cluster ID. but the python sample code always failed with below errors: Traceback (most recent call last): File "/root/pixie-api-example/main.py", line 26, in main() ~~~~^^ File "/root/pixie-api-example/main.py", line 9, in main conn = px_client.connect_to_cluster('a355537a-8962-4b28-94ee-64e34479e912') File "/root/pixie-api-example/.venv/lib/python3.13/site-packages/pxapi/client.py", line 588, in connect_to_cluster cluster_info = self._get_cluster_info(cluster_id) File "/root/pixie-api-example/.venv/lib/python3.13/site-packages/pxapi/client.py", line 555, in _get_cluster_info return self._get_cluster(request)[0] ~~~~~~~~~~~~~~~~~^^^^^^^^^ File "/root/pixie-api-example/.venv/lib/python3.13/site-packages/pxapi/client.py", line 530, in _get_cluster response: cpb.GetClusterInfoResponse = stub.GetClusterInfo(request, metadata=[ ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^ ("pixie-api-key", self._token), ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ("pixie-api-client", "python") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ]) ^^ File "/root/pixie-api-example/.venv/lib/python3.13/site-packages/grpc/_channel.py", line 1181, in call return _end_unary_response_blocking(state, call, False, None) File "/root/pixie-api-example/.venv/lib/python3.13/site-packages/grpc/_channel.py", line 1006, in _end_unary_response_blocking raise _InactiveRpcError(state) # pytype: disable=not-instantiable ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with: status = StatusCode.INTERNAL details = "Auth middleware failed: failed to fetch token - unauthenticated" debug_error_string = "UNKNOWN:Error received from peer ipv4:34.102.151.106:443 {created_time:"2025-06-10T10:22:11.997274906+08:00", grpc_status:13, grpc_message:"Auth middleware failed: failed to fetch token - unauthenticated"}"

I tried the apikey with/without the prefix of "px-api-", but all failed. I also unset the system proxy settings, but still no effect.

I added server_url to my self-hosted cloud, but failed with no certificaiton. px_client = pxapi.Client(token="px-api-03397708-2978-4710-9beb-e40e38096e57", server_url="dev.withpixie.dev", use_encryption=False)

Hi @everestplusteam, can you verify that your API key exists with the px cli. You can do so by running the following command:

$ PX_CLOUD_ADDR=dev.withpixie.dev:443 px api-key lookup
> Enter API Key (won't echo):  <Enter your key in the prompt>

Please provide the output for that command once you've had a chance to run it.

it is my output, but I still cannot connect to with my API key.

I resolved the issue, as local cluster used, I need to set the cluster_address instead using the default value.
