Agent API access

Hi there Lisa MM

Thanks for using QandA platform

If your agent works in Playground but API access via project key returns a 401 Unauthorized, it’s possible that external API access for your Foundry project is not enabled by default.

We cant check it for you please check if your Azure subscription and Foundry project settings permit external API access. Also, verify that the project key is correct, the API endpoint is Correct

If this helps kindly accept the answer thanks much.

Hi Lisa MM

If you're encountering a 401 Unauthorized error in Azure AI Foundry, follow these steps:

• Check API Access Settings: Go to Azure Portal → AI Foundry Project → Networking and confirm external access settings.
• Verify API Key & Headers: Ensure the request includes -H "api-key: " instead of Authorization.
• Confirm Subscription & Permissions: Check that your subscription is active and has the correct RBAC roles.
• Review API Documentation: Refer to Azure AI Foundry API Access Guide for authentication details.
• Test & Debug: Try an API call in Playground, validate headers, and check endpoint correctness.

I Hope this helps. Do let me know if you have any further queries. If this answers your query, please do click Accept Answer and Yes for was this answer helpful.
