CORS Support

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

Rate Limiting

ZIP Demographics API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all ZIP Demographics users.

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each ZIP Demographics response includes headers to help you track your usage:

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, ZIP Demographics returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for ZIP Demographics:

  • Monitor the rate limit headers to track your ZIP Demographics usage (Free plan only)
  • Cache zip demographics responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle ZIP Demographics performance

Note: ZIP Demographics rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using ZIP Demographics on Free tier.

Error Codes

The ZIP Demographics API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
