Where keys come from

API keys are issued from your Dashboard. Every key starts with sk-orca-.

​
How to send the key

Send your key via the standard Authorization header: 
Authorization: Bearer sk-orca-...
This works for every endpoint and every supported SDK (OpenAI, Anthropic, google-genai, etc.) — point the SDK’s base_url at https://api.orcarouter.ai/v1 and pass the sk-orca-... value as the api_key.

​
Per-key options at creation

When you create a key in the dashboard, you can set:
  • Name — a label so you remember what the key is for
  • Credit limit — cap on total spend in USD; leave blank for unlimited (within your account’s overall balance)
  • Expiration — a fixed lifetime (1 hour up to 1 year, or never)
That’s everything. There’s no per-key rate-limit override and no per-key model allowlist on the user side; rate limits are applied at the workspace level (see Rate Limits).
