Headers
Required and optional headers for API requests:
| Header Name | Required | Example Value | Description |
|---|---|---|---|
X-API-Key | Yes | your_api_key_here | Your APIVerve API key. Found in your dashboard under API Keys. |
Accept | No | application/json | Specify response format: application/json (default), application/xml, or application/yaml |

GraphQL AccessALPHA
Most APIVerve APIs support GraphQL queries, allowing you to combine multiple API calls into a single request and retrieve only the data you need. This powerful feature enables you to orchestrate complex data fetching with precise field selection.
Not all APIs support GraphQL. Check the API schema or test in the GraphQL Explorer to confirm availability for this specific endpoint.
Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

CORS Support
The County Data Lookup API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call County Data Lookup directly from browser-based applications without proxy servers.
| CORS Header | Value | Description |
|---|---|---|
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 |
Browser Usage: You can make direct API calls from JavaScript running in the browser without encountering CORS errors. No additional configuration needed.
Rate Limiting
APIVerve implements rate limiting to ensure fair usage and maintain service quality across all users. Rate limits vary by subscription plan and are applied per API key.
| Plan | Rate Limit | Description |
|---|---|---|
| Free | 5 requests/min | Hard rate limit enforced - exceeding will return 429 errors |
| Starter | No Limit | Production ready - no rate limiting or throttling |
| Pro | No Limit | Production ready - no rate limiting or throttling |
| Mega | No Limit | Production ready - no rate limiting or throttling |
Rate Limit Headers
When rate limits apply, each API response includes headers to help you track your usage:
| Header | Description |
|---|---|
X-RateLimit-Limit | Maximum number of requests allowed per time window |
X-RateLimit-Remaining | Number of requests remaining in the current window |
X-RateLimit-Reset | Unix timestamp when the rate limit window resets |
Handling Rate Limits
Free Plan: When you exceed your rate limit, County Data 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:
- Monitor the rate limit headers to track your usage (Free plan only)
- Implement caching where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle performance
Note: Rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits on Free tier.
Client Libraries
To get started with minimal code, most of our APIs are available through client libraries and clients:
Error Codes
The County Data Lookup API uses standard HTTP status codes to indicate success or failure:
| Code | Message | Description | Solution |
|---|---|---|---|
200 | OK | Request successful, data returned | No action needed - request was successful |
400 | Bad Request | Invalid request parameters or malformed request | Check required parameters and ensure values match expected formats |
401 | Unauthorized | Missing or invalid API key | Include x-api-key header with valid API key from dashboard |
403 | Forbidden | API key lacks permission or insufficient credits | Check credit balance in dashboard or upgrade plan |
429 | Too Many Requests | Rate limit exceeded (Free: 5 req/min) | Implement request throttling or upgrade to paid plan |
500 | Internal Server Error | Server error occurred | Retry request after a few seconds, contact support if persists |
503 | Service Unavailable | API temporarily unavailable | Wait and retry, check status page for maintenance updates |

Frequently Asked Questions
How do I get an API key?
What are credits and how do they work?
Credits are your API usage currency. Each successful API call consumes credits based on the API's complexity. Most APIs cost 1 credit per call, while more complex APIs may cost 2-5 credits. Failed requests and errors don't consume credits. Check the API details above to see the credit cost for this specific API.
Can I use County Data Lookup in production?
The free plan is for testing and development only. For production use of County Data Lookup, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.
Can I use County Data Lookup from a browser?
What happens if I exceed my credit limit?
When you reach your monthly credit limit, API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
