hi, want to get started sending traces to arize. https://arize.com/docs/phoenix/tracing/how-to-tracing/setup-tracing/setup-using-phoenix-otel question: what's the endpoint for the cloud env to set here?
To get started sending traces to Arize (Phoenix), install the arize-phoenix-otel package and use the phoenix.otel.register function to configure tracing. Set the PHOENIX_COLLECTOR_ENDPOINT environment variable to your Phoenix endpoint, and optionally set PHOENIX_API_KEY or PHOENIX_CLIENT_HEADERS for authentication. Then, call register() in your code to initialize tracing and auto-instrument supported libraries.Example: LBKSimport os os.environ["PHOENIX_COLLECTOR_ENDPOINT"] = "https://your-phoenix.com:6006" from phoenix.otel import register tracer_provider = register(project_name="my-project", auto_instrument=True)LBKSFor more details, see the official setup guide.Would you like more detail or a full example for a specific language or framework?Sources:
- Setup using Phoenix OTEL
馃挕聽Hint: Mention RunLLM in the thread for followups.
The Phoenix Cloud endpoint is https://app.phoenix.arize.com. For sending traces, use https://app.phoenix.arize.com/v1/traces as the OTEL tracing endpoint. You can find your specific endpoint under the Hostname field in your Phoenix Cloud Settings page if needed.Would you like more detail on configuring your client or authentication?Sources: - What is my Phoenix Endpoint? - What is my Phoenix Endpoint?

getting a lot:
Failed to export batch code: 401, reason:
Failed to export batch code: 401, reason:after this python:
from phoenix.otel import register
import openai
register(
project_name="joke-evaluation-langgraph",
headers={
"space_id": os.getenv("ARIZE_SPACE_ID"),
"api_key": os.getenv("ARIZE_API_KEY"),
},
endpoint="https://app.phoenix.arize.com/v1/traces",
batch=True,
auto_instrument=True
)
The 401 error means authentication failed. For Phoenix Cloud, you should set the PHOENIX_API_KEY environment variable (not headers) and omit custom headers鈥擯hoenix expects the API key as an authorization header, not as api_key or space_id in headers. Example: LBKSimport os os.environ["PHOENIX_API_KEY"] = "<YOUR_API_KEY> " from phoenix.otel import register register( project_name="joke-evaluation-langgraph", endpoint="https://app.phoenix.arize.com/v1/traces", batch=True, auto_instrument=True )LBKSDo not include "space_id" or "api_key" in headers for Phoenix Cloud. See official docs and authentication guide.Would you like more troubleshooting steps?Sources:

RunLLM still:
from phoenix.otel import register
import openai
print(f"Phoenix api key is: {os.getenv('PHOENIX_API_KEY')}")
register(
project_name="joke-evaluation-langgraph",
endpoint="https://app.phoenix.arize.com/v1/traces",
batch=True,
auto_instrument=True
)
self.client = openai
self.callbacks = []
same issue
The 401 error will persist if the PHOENIX_API_KEY environment variable is not set in the current process before calling register(). Also, remove the angle brackets <> from the endpoint URL. Set the environment variable like this before running your script: LBKSimport os os.environ["PHOENIX_API_KEY"] = "<YOUR_API_KEY> " # No angle brackets in the actual valueLBKSAnd use: LBKSregister( project_name="joke-evaluation-langgraph", endpoint="https://app.phoenix.arize.com/v1/traces", batch=True, auto_instrument=True )LBKSIf you still get 401, double-check that your API key is valid and not expired.

should the key start with a value like this?
PHOENIX_API_KEY=ak-fefb29aa-RunLLM i just generated the key here: https://app.arize.com/account/api-keys ... is that correct?
It seems likely that the correct API key for Phoenix Cloud should be generated from the Phoenix Cloud UI at https://app.phoenix.arize.com/ (not https://app.arize.com/account/api-keys, which is for Arize, not Phoenix). Phoenix API keys typically do not start with ak-; they are usually long alphanumeric strings without a prefix like that.Please generate your API key from the Phoenix Cloud settings page as described in the official docs. Using an Arize (ak-) key will result in authentication errors.Would you like step-by-step instructions for generating the correct Phoenix API key?Sources: - official docs

You are still getting a 401 because the API key is likely not a valid Phoenix Cloud key.

You must generate your API key from the Phoenix Cloud UI (instructions here), and it should not start with ak-.Please ensure you are using a Phoenix Cloud API key from https://app.phoenix.arize.com/settings/api-keys, set as PHOENIX_API_KEY, and remove any angle brackets from the endpoint.Would you like step-by-step instructions for generating and using the correct key?Sources: - https://github.com/Arize-ai/phoenix/issues/5162 - https://github.com/Arize-ai/phoenix/blob/main/docs/tracing/how-to-tracing/setup-tracing/setup-using-phoenix-otel.md

got it lol, what a mediocre getting started docu
Peter are you attempting to send traces to Arize AX or Phoenix Cloud? These are two different products with two different API keys and authentication schemes. You may be looking for this documentation https://arize.com/docs/ax/observe/quickstart-llm
Further support for AX can be found in Arize AX Support, or, if you'd like to use Phoenix Cloud instead you can sign in to https://app.phoenix.arize.com
My goal was to run this agent evaluations and to try it out: https://arize.com/docs/ax/arize-ai-for-agents
