Rate Limiting

The API implements rate limiting to prevent abuse:

  • Default Limit: 100 requests per minute per API key
  • Window: 60 seconds (sliding window)
  • Response Header: X-RateLimit-Remaining shows remaining requests

When rate limit is exceeded:

HTTP/1.1 429 Too Many Requests
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 1609459200

Response Time SLA

Inquiry Type Target Response Time Timeout
Person < 2 seconds 10 seconds
Real Estate < 3 seconds 10 seconds
Shahkar < 1.5 seconds 10 seconds
Postal Code < 1 second 10 seconds
Sheba < 2 seconds 10 seconds

Best Practices

1. Always Include Tracking Code

Store the trackingCode from responses for troubleshooting and support requests.

2. Handle Errors Gracefully

Implement retry logic with exponential backoff for transient errors (5xx).

3. Validate Input Client-Side

Validate national codes, postal codes, and mobile numbers before sending requests.

4. Use Appropriate Timeouts

Set client-side timeouts slightly higher than API timeouts (e.g., 12 seconds).

5. Monitor Rate Limits

Track X-RateLimit-Remaining header and implement client-side throttling.

6. Log All Requests

Log request/response pairs with tracking codes for audit and debugging.

7. Secure API Keys

  • Never expose API keys in client-side code
  • Rotate keys regularly
  • Use environment variables
  • Implement key rotation without downtime
