GraphQL AccessALPHA

Access Zip Codes Lookup through GraphQL to combine it with other API calls in a single request. Query only the zip codes lookup data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

POST https://api.apiverve.com/v1/graphql

query {
  zipcodes(
    input: {
      zip: "64082"
    }
  ) {
    zipcode
    state_abbr
    latitude
    longitude
    city
    state
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Zip Codes Lookup API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Zip Codes Lookup directly from browser-based applications without proxy servers.

Browser Usage: You can call Zip Codes Lookup directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

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

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Zip Codes Lookup response includes headers to help you track your usage:

Handling Rate Limits

Free Plan: When you exceed your rate limit, Zip Codes Lookup 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 Codes Lookup:

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

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

Error Codes

The Zip Codes Lookup API uses standard HTTP status codes to indicate success or failure:
