1. Get three things readyCopy Anchor Link

• API address: open this site’s connection settings and copy the address required below.
• API key: create or copy a key in API key management. Do not use your login password.
• Model ID: copy the exact ID from the model list, not its display name.

Use an address and key from the same site. Domestic and overseas credentials are separate.

2. Configure Claude CodeCopy Anchor Link

Replace these values in the example; do not leave YOUR_... unchanged:

Set these variables in the terminal that launches Claude Code:

export ANTHROPIC_BASE_URL='YOUR_ANTHROPIC_BASE_URL'
export ANTHROPIC_AUTH_TOKEN='YOUR_API_KEY'
export ANTHROPIC_MODEL='YOUR_CLAUDE_MODEL_ID'
claude

Use the API root without /v1; Claude Code appends /v1/messages. Select an available Claude model and use /status to check the address and model.

3. Send a test messageCopy Anchor Link

Select the model you just configured, open a new chat, and send:

Please reply with only: Connected

A normal reply means your first connection worked. You can now start your own task.

If no reply arrives, check the error:

• 401 / API key error: copy the full key again and check that the address and key belong to the same site.
• 404 / endpoint not found: compare the URL with the format above, especially missing or repeated /v1.
• Model not found: copy the exact model ID again and check that your key has access.

See Troubleshooting for other errors. To check the API separately, use the first request example.
