Authentication & Rate Limits

API Keys

Currently, the WheelX API is publicly accessible. API key authentication will be introduced for:

• Higher rate limits
• Priority routing
• Advanced features

Rate Limits

Tier	Limit	Window
Public	20 requests	Per minute
API Key (future)	Coming soon	Coming soon

Rate Limit Response

When rate limited, the API returns:

HTTP 429 Too Many Requests

Best Practices

• Implement exponential backoff on 429 responses
• Cache chain-info responses (change infrequently)
• Use webhooks instead of polling for order status
