Distance Calculator API
Distance Calculator is a simple tool for calculating the distance between two locations. It returns the distance in miles and kilometers.
The Distance Calculator API provides reliable and fast access to distance calculator data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.
To use Distance Calculator, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA
Access Distance Calculator through GraphQL to combine it with other API calls in a single request. Query only the distance calculator 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/graphqlquery {
distancecalculator(
input: {
lat1: 36.7783
lon1: -119.4179
lat2: 34.0522

}Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.
CORS Support
The Distance Calculator API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Distance Calculator 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 call Distance Calculator directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.
Rate Limiting
Distance Calculator API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Distance Calculator users.
| Plan | Rate Limit | Description |
|---|---|---|
| Free | 5 requests/min | Hard rate limit enforced - exceeding will return 429 errors |
| Starter | No Limit | Production ready - standard traffic priority |
| Pro | No Limit | Production ready - preferred traffic priority |
| Mega | No Limit | Production ready - highest traffic priority |

Rate Limit Headers
When rate limits apply, each Distance Calculator 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, Distance Calculator 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 Distance Calculator:
- Monitor the rate limit headers to track your Distance Calculator usage (Free plan only)
- Cache distance calculator responses where appropriate to reduce API calls
- Upgrade to Pro or Mega for guaranteed no-throttle Distance Calculator performance
Note: Distance Calculator rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Distance Calculator on Free tier.
Error Codes
The Distance Calculator 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 for Distance Calculator?
How many credits does Distance Calculator cost?
Each successful Distance Calculator API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful distance calculator lookups.
Can I use Distance Calculator in production?
The free plan is for testing and development only. For production use of Distance Calculator, 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 Distance Calculator from a browser?
What happens if I exceed my Distance Calculator credit limit?
When you reach your monthly credit limit, Distance Calculator 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.
