Authentication

Datzi supports OAuth and API keys for model providers. For Anthropic accounts, we recommend using an API key. For Claude subscription access, use the long‑lived token created by claude setup-token. See /concepts/oauth for the full OAuth flow and storage layout.

Checking model auth status

datzi models status
datzi doctor

​
API key rotation behavior (gateway)

Some providers support retrying a request with alternative keys when an API call hits a provider rate limit.
  • Priority order:
    • DATZI_LIVE_<PROVIDER>_KEY (single override)
    • <PROVIDER>_API_KEYS
    • <PROVIDER>_API_KEY
    • <PROVIDER>_API_KEY_*
  • Google providers also include GOOGLE_API_KEY as an additional fallback.
  • The same key list is deduplicated before use.
  • Datzi retries with the next key only for rate-limit errors (for example 429, rate_limit, quota, resource exhausted).
  • Non-rate-limit errors are not retried with alternate keys.
  • If all keys fail, the final error from the last attempt is returned.

​
Controlling which credential is used

​
Per-session (chat command)

Use /model <alias-or-id>@<profileId> to pin a specific provider credential for the current session (example profile ids: anthropic:default, anthropic:work). Use /model (or /model list) for a compact picker; use /model status for the full view (candidates + next auth profile, plus provider endpoint details when configured).

​
Per-agent (CLI override)

Set an explicit auth profile order override for an agent (stored in that agent’s auth-profiles.json): 
datzi models auth order get --provider anthropic
datzi models auth order set --provider anthropic anthropic:default
datzi models auth order clear --provider anthropic
Use --agent <id> to target a specific agent; omit it to use the configured default agent.

​
Troubleshooting

​
“No credentials found”

If the Anthropic token profile is missing, run claude setup-token on the gateway host, then re-check: 
datzi models status

​
Token expiring/expired

Run datzi models status to confirm which profile is expiring. If the profile is missing, rerun claude setup-token and paste the token again.

​
Requirements

  • Claude Max or Pro subscription (for claude setup-token)
  • Claude Code CLI installed (claude command available)
