# Google Vertex AI (Meta Muse) — Bring Your Own Key

Use Meta Muse models from your own Google Cloud project. AnyRouter calls Agent Platform (publishers/meta) with your service account, so Google bills you directly.

## Get your API key

1. In the [Google Cloud console](https://console.cloud.google.com/agent-platform/model-garden), open the **Model Garden**, find the Meta Muse models (Muse Ember 1.0, Muse Spark 1.3, Muse Wonder 1.0) and enable them for your project.
2. Create a service account with the **Vertex AI User** role and download its JSON key.
3. Paste the service-account JSON into AnyRouter. The Muse models are served on the `global` endpoint only, so no region field is needed.

## Gotchas

Muse models are Preview (Pre-GA Offerings Terms) and pay-as-you-go on the `global` endpoint only — they are not available in express mode, and API keys are rejected ("API keys are not supported by this API"). AnyRouter authenticates with an OAuth2 token minted from your service account via AI Gateway.

## Add it to AnyRouter

1. Open **[Dashboard → BYOK](https://anyrouter.dev/dashboard/byok)**, find **Google Vertex AI (Meta Muse)** under **Available** and click **Add key**.
2. Paste the key.
3. Click **Save**. AnyRouter validates the key against Google Vertex AI (Meta Muse) first; on failure the dialog shows the upstream error and nothing is saved.
