Add your OrcaRouter endpoint to access 200+ models in Arize AX’s prompt playground and LLM-as-a-judge evaluations. OrcaRouter exposes a single OpenAI-compatible endpoint, so it is added as a Custom Model Endpoint — Arize AX makes use of the OpenAI Client to make calls to it. OrcaRouter supports a orcarouter/auto virtual model that selects an upstream provider per request, as well as specific provider models using a <provider>/<model> identifier.
By adding this integration, your data may be sent through OrcaRouter to the underlying model provider for certain actions within Arize AX (e.g., prompt playground) and your account may be billed for usage.

Add the Integration Using the Arize Skills

Add an OrcaRouter integration from your coding agent using the Arize Skills:

Create a custom model integration named 'my-orcarouter' with my base URL https://api.orcarouter.ai/v1 and API key sk-orca-...

Add the Integration from Arize AX

Select Custom Model Endpoints from the Providers List

The AI Provider integrations tab

Fill Out Your Integration Details

The OrcaRouter integration details pane
Give your integration a name (e.g. OrcaRouter). Then set your base URL and an OrcaRouter API key from the OrcaRouter dashboard.
Enter the base URL: https://api.orcarouter.ai/v1. Do not include endpoint paths like /chat/completions as these are appended automatically.
If you need to send any extra headers to every request, set these. You then need to define the available model deployments. Leave OpenAI default models off and add your OrcaRouter model identifiers as custom model names. Add orcarouter/auto to use the virtual routing model, or add specific provider models in <provider>/<model> format (e.g. openai/gpt-4.1, anthropic/claude-sonnet-4-6).

Advanced Settings

The AI integration details tab
Expand the Advanced Settings section to configure the following:
  • Supports Function Calling - Turn this on to allow the integration to use function calling features. This is on by default.
  • Authorized Orgs - Configure which organizations have access to this integration.
  • Authorized Spaces - Configure which spaces have access to this integration.

Add the Integration
