## Rate Limits

The server implements rate limiting to comply with DexScreener's API limits:
- Token Profile/Boost endpoints: 60 requests per minute
- DEX/Pairs endpoints: 300 requests per minute

## Error Handling

The server handles various error scenarios:
- Rate limit exceeded
- Invalid parameters
- Network errors
- API errors

Errors are returned in a standardized format with appropriate error codes and messages.
