GraphQL AccessALPHA

Access Subdomain Finder through GraphQL to combine it with other API calls in a single request. Query only the subdomain finder data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Subdomain Finder in the GraphQL Explorer to confirm availability and experiment with queries.

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

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  subdomainfinder(
    input: {
      domain: "google.com"
      limit: 5
    }
  ) {
    rootDomain {
      domain
      records
    }
    subDomains
    count
    totalFound
  }
}

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

CORS Support

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

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

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

Rate Limiting

Subdomain Finder API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Subdomain Finder 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 Subdomain Finder 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, Subdomain Finder 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 Subdomain Finder:

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

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

The Subdomain Finder API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution

How many credits does Subdomain Finder cost?

What happens if I exceed my Subdomain Finder credit limit?
