Best Practices

Monitor Usage

// Check balance before expensive operations
async function checkCredits(required) {
  const response = await fetch(
    'https://api.percify.io/v1/user/credits/balance',
    {
      headers: {
        'Authorization': `Bearer ${process.env.PERCIFY_API_KEY}`
      }
    }
  );
  
  const credits = await response.json();
  
  if (credits.balance < required) {
    throw new Error(
      `Insufficient credits. Required: ${required}, Available: ${credits.balance}`
    );
  }
  
  return credits.balance;
}

Set Up Webhooks

Alert when balance is low
Track usage patterns
Automate credit purchases
Monitor tier limits

Optimize Credit Usage
