API Key Authentication

All API requests (except /health) require an API key passed via the X-API-Key header: 
curl "https://api.arbiterapi.com/v1/markets" \
  -H "X-API-Key: arb_live_abc123..."

​
Getting an API Key

​
Option 1: Sign up via API

curl -X POST "https://api.arbiterapi.com/v1/auth/signup" \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com", "password": "your-password"}'

​
Option 2: Dashboard

Sign up at arbiterapi.com/signup to get your key from the dashboard.

​
Managing Keys

You can create multiple API keys per account and revoke them individually: 
# List your keys
curl .../v1/keys -H "Authorization: Bearer YOUR_JWT"

# Create a new key
curl -X POST .../v1/keys \
  -H "Authorization: Bearer YOUR_JWT" \
  -H "Content-Type: application/json" \
  -d '{"label": "production"}'

# Revoke a key
curl -X DELETE .../v1/keys/key_id \
  -H "Authorization: Bearer YOUR_JWT"

​
WebSocket Authentication

For WebSocket connections, pass your API key as a query parameter:
