Azure Foundry (Claude) (BYOK)

How to create an API key for Azure Foundry (Claude) and add it to AnyRouter via Bring Your Own Key.

Use Claude from your own Microsoft Foundry resource. AnyRouter calls your resource directly, so Azure bills you through your Marketplace subscription.

Get your API key

  1. In Microsoft Foundry, open Discover → Models, pick a Claude model and Deploy it. Keep the default deployment name (the model name).
  2. Open the deployment and copy the resource endpoint (https://<resource>.services.ai.azure.com) and the API key.
  3. Paste a JSON object into AnyRouter: { "endpoint_url": "https://<resource>.services.ai.azure.com", "api_key": "<key>" }.

Gotchas

If you renamed a deployment, add a "deployments" map from the model id to your name, for example { "claude-sonnet-4-6": "my-sonnet" }. Claude on Foundry needs a pay-as-you-go Azure subscription; student, trial and credit-only subscriptions cannot deploy it.

Add it to AnyRouter

  1. Go to Dashboard → BYOK.
  2. Find Azure Foundry (Claude) under Available and click Add key.
  3. Paste your key into the API key field.
  4. Click Save. AnyRouter runs a live validation call against Azure Foundry (Claude) before storing the key — if it fails, the dialog shows the upstream error and the key isn't saved.
