How to Fix 401 Unauthorized Error on Arize API in Postman and API Key Usage

·Jan 18, 2026 06:30 PM·

Hi, I am getting 401 unauthorized error when trying to run the api app.arize.com/api/graphql/v1 on postman. I tried with ingestion and developer keys but no luck. What API key should I use for this endpoint? Also, are there curls documented anywhere for traces, spantree, evaluations etc?

What graphql query should I use to retrieve traces, span tree and evaluations?

🔒[private user], we are building an application to retrieve traces, span tree from arize with the same schema as the Arize AX UI does. It's not that straight forward with Python SDK. The UI calls REST APIs to get the data. Are these APIs exposed outside Arize?

We don't want to reinvent the wheel. Just want to call existing APIs and use the same schema to show the data on our application.

We're using Arize AX as our enterprise application, so Phoenix cannot be used for our purposes. Is this endpoint accessible outside Arize? app.arize.com/api/graphql/v1 If so, how do I create the bearer token for the authentication?
