# Claude Code

> Use a Valkyrie-hosted model as Claude Code's model.

Claude Code speaks the **Anthropic Messages protocol**, and Valkyrie serves your
deployed model over that same protocol. Point Claude Code at your deployment by
setting its Anthropic base URL and auth token. The base URL is your API host plus the
deployment **slug** (`deployment-{id}`) or an [alias](/guides/aliases). Claude Code
appends `/v1/messages` itself.

```bash theme={null}
# By deployment slug (deployment-{id})
export ANTHROPIC_BASE_URL="https://valkyrie-back.azumo.com/deployment-213"
# ...or by alias:
# export ANTHROPIC_BASE_URL="https://valkyrie-back.azumo.com/{account_slug}/{alias}"

export ANTHROPIC_AUTH_TOKEN="vk_dep_your_deployment_key"

claude
```

<Note>
  Valkyrie exposes `/{deployment_slug}/v1/messages` and
  `/{deployment_slug}/v1/messages/count_tokens` (and the alias equivalents). Use a
  **deployment key** (`vk_dep_`); it's accepted as `ANTHROPIC_AUTH_TOKEN` or as the
  `x-api-key` header the Anthropic SDKs send. An [alias](/guides/aliases) gives you a
  stable base URL to bake into your shell profile.
</Note>

<Warning>
  A self-hosted open model is not Claude. Behavior, tool-use quality, and context
  limits depend entirely on the model you deployed. Size the deployment for the
  workload you expect from a coding agent.
</Warning>

<Info>
  Looking to let Claude Code **operate Valkyrie** (deploy models, read logs, manage
  jobs) rather than use one as its model? That's the MCP server, see
  [Set up the MCP server](/mcp/setup#claude-code). The two integrations are
  independent and can be used together.
