AUTHENTICATION
Authentication & Account
Learn how to create an account, manage API keys, and authenticate your requests.
Account Setup
Create an Account
Create an llm.market account, verify your email, then create an API key in the dashboard.
Get Your API Key
After signing in, create an API key in the Dashboard. Copy its raw value immediately; it is not stored for later display.
Make Your First Request
Use your API key in the Authorization header to authenticate requests to any endpoint.
API Key Management
Primary API Key
Every account gets a primary key with full access. This key cannot be deleted but can be regenerated.
Secondary API Keys
Create additional keys with custom RPM limits, credit allowance, and labels for applications.
Authentication Methods
Include your API key in the Authorization header as a Bearer token.
curl https://llm.market/v1/chat/completions \
-H "Authorization: Bearer sk-YOUR_LLM_MARKET_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"MODEL_FROM_V1_MODELS","messages":[{"role":"user","content":"Hello!"}]}'Never share your API key publicly, commit it to version control, or expose it in client-side code. Treat it like a password.
