Claude Code

Claude Code uses the Anthropic Messages protocol. With QuotaAPI, set the Base URL to https://quotarouter.ai and use the API Key created in the console.

Environment variables

Set:

export ANTHROPIC_BASE_URL="https://quotarouter.ai"
export ANTHROPIC_AUTH_TOKEN="YOUR_QUOTAAPI_KEY"

If your client version expects ANTHROPIC_API_KEY, use:

export ANTHROPIC_BASE_URL="https://quotarouter.ai"
export ANTHROPIC_API_KEY="YOUR_QUOTAAPI_KEY"

Restart the terminal or Claude Code so the updated environment is loaded.

cc-switch import

If you manage profiles with cc-switch, keep these fields aligned:

Field	Value
Provider	Anthropic compatible
Base URL	https://quotarouter.ai
API Key	YOUR_QUOTAAPI_KEY
Model	claude-opus-4.8 or a Claude model enabled in the console

After importing, run a short prompt before switching to production work.

Manual Anthropic Messages test

curl https://quotarouter.ai/v1/messages \
  -H "x-api-key: YOUR_QUOTAAPI_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-4.8",
    "max_tokens": 80,
    "messages": [
      { "role": "user", "content": "Reply with one sentence about QuotaAPI." }
    ]
  }'

Model names

Use the model names enabled in your console. Common Claude examples:

Model	Good for
claude-opus-4.8	Complex reasoning, long context and coding tasks
claude-sonnet-4.5	Daily development, Q&A and cost-sensitive work

If the client reports that a model is missing, check that the API Key has access to the Claude group and that the model name is spelled exactly as shown in the console.

Troubleshooting

• Authentication fails: check whether ANTHROPIC_AUTH_TOKEN or ANTHROPIC_API_KEY contains your QuotaAPI Key.
• Requests still hit the default official URL: ANTHROPIC_BASE_URL was not loaded. Restart the terminal or check profile files.
• Insufficient balance: open the console and review balance and request records.
• Model unavailable: check group permissions and model name.
