Conectar Claude Code

Claude Code utiliza Anthropic Messages API. Define ANTHROPIC_BASE_URL con la raíz de NordRouter, sin /v1, y proporciona la clave y el modelo mediante variables de entorno o settings.json.

Se recomienda ~/.claude/settings.json para compartir la configuración entre terminal y VS Code.
No añadas /v1: Claude Code incorpora /v1/messages por sí mismo.
Ante un inicio de sesión, 401 o /v1/v1, revisa por orden la opción de login, la clave y la 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
