Claude Code

Claude Code talks to NagaAI through /v1/messages. Install it from the official guide, then add the settings below. Setup follows the Claude Code LLM gateway guide.

Configure

Put the variables in ~/.claude/settings.json. Values in env of a settings file take precedence over the shell. A project .claude/settings.local.json works too, after you accept the trust prompt for that folder.

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.naga.ac",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_NAGAAI_API_KEY",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-5.5",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-5",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4.5",
    "ANTHROPIC_DEFAULT_FABLE_MODEL": "claude-fable-5.1",
    "CLAUDE_CODE_SUBAGENT_MODEL": "claude-sonnet-5",
    "CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY": "1"
  }
}

ANTHROPIC_AUTH_TOKEN sends the key as Authorization: Bearer. Set all four ANTHROPIC_DEFAULT_*_MODEL variables: Claude Code’s built-in aliases expand to ids such as claude-opus-5-5, while NagaAI ids use a dot. Any chat model from the catalog works in these slots, not only Claude models, as long as it supports tools. With model discovery on, /model lists the Claude models from /v1/models. Start claude and run /status to see the base URL and model in use.

Limits through NagaAI

No prompt caching. NagaAI drops cache_control, so Claude models get no cache hits and every turn costs full input price. Long sessions cost more than on a direct Anthropic account with caching.
No token counting. count_tokens returns 404. Claude Code then estimates context size, so /context shows approximate numbers.
Beta features. NagaAI ignores anthropic-beta headers, so features that depend on them are off.
