Collegare Claude Code

Claude Code usa Anthropic Messages API. Imposta ANTHROPIC_BASE_URL sulla radice NordRouter senza /v1 e fornisci chiave e modello tramite variabili d'ambiente o settings.json.

• ~/.claude/settings.json condivide la configurazione tra terminale e VS Code.
• Non aggiungere /v1: Claude Code aggiunge /v1/messages.
• In caso di login, 401 o /v1/v1 controlla opzione di accesso, chiave e indirizzo.

Documentazione ufficiale e collegamenti

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

Verifica prima la connessione con una richiesta testuale minima, quindi aggiungi streaming, chiamate agli strumenti, immagini e altre funzioni avanzate. Non inserire mai la chiave API in codice pubblico o nel frontend del browser.
