連接 Claude Code

Claude Code 使用 Anthropic Messages API。設定 ANTHROPIC_BASE_URL 為 NordRouter 根位址（不含 /v1），並透過環境變數或 settings.json 提供金鑰與模型。

建議使用使用者層級的 ~/.claude/settings.json，讓終端與 VS Code 共用設定。
Base URL 不含 /v1，因為 Claude Code 會自行加入 /v1/messages。
若出現登入提示、401 或 /v1/v1，請依序檢查登入停用選項、金鑰與 Base URL。

Variable	Meaning
`ANTHROPIC_API_KEY`	Your `sk-nr-…` key
`ANTHROPIC_BASE_URL`	`https://nordrouter.com` — no trailing `/v1`
`ANTHROPIC_MODEL`	Main model. You can also set `anthropic/claude-sonnet-5` or `anthropic/claude-fable-5`
`ANTHROPIC_DEFAULT_*_MODEL`	So the `/model opus\|sonnet\|haiku` command picks the correct IDs from our catalog
`ANTHROPIC_SMALL_FAST_MODEL`	Fast background model for Claude Code's utility tasks

Error	Cause	Fix
`Missing Bearer API key`	The key wasn't picked up: empty `ANTHROPIC_API_KEY` or an `"apiKeyHelper": "echo ''"` line in the config	Set the key; delete the `apiKeyHelper` line
`Auth conflict: Both a token … and an API key are set` + endless retries	A stale `ANTHROPIC_AUTH_TOKEN` (from a previous login) overrides your key — the server receives the wrong credential and returns 401	Unset it: `$env:ANTHROPIC_AUTH_TOKEN = $null` (Windows) / `unset ANTHROPIC_AUTH_TOKEN` (macOS/Linux); make sure it's not in `settings.json`
`Invalid URL (POST /v1/v1/messages)`	`/v1` appended to `ANTHROPIC_BASE_URL`	Remove `/v1`: it must be exactly `https://nordrouter.com`
`No pricing available for model claude-opus-5`	Claude Code requests a model by its "bare" ID	Set `ANTHROPIC_MODEL` and `ANTHROPIC_DEFAULT_*_MODEL` as in the config above
`Invalid or malformed JSON` in settings.json	Broken JSON: missing braces/commas or "smart" quotes pasted from a chat	Replace the file contents entirely with the config above
`Invalid API key`	Typo in the key, or the key was deleted	Check the key in the dashboard
