gateway.ngrok.ai

When troubleshooting issues with the current AI Gateway at https://gateway.ngrok.ai:
  1. Check the error code and message in the response body. See Error Codes.
  2. Verify your app sends an access key—not an upstream provider key.
  3. Confirm the access key’s configuration allows the provider and model you requested, with routing credentials attached.
  4. Review usage in Observability.
Common fixes: See Error Handling for retry and failover behavior.

Legacy endpoint setup

If you still run the AI Gateway as a Traffic Policy action on a custom ngrok endpoint, action result variables like ${actions.ngrok.ai_gateway} are available in Traffic Policy expressions. See Migrating from endpoints to move to gateway.ngrok.ai.
