Headers

Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →

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 accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Subdomain Finder requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Subdomain Finder API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →

Frequently Asked Questions

How do I get an API key for Subdomain Finder?

Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for Subdomain Finder and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.

How many credits does Subdomain Finder cost?

Each successful Subdomain Finder 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 subdomain finder lookups.

Can I use Subdomain Finder in production?

The free plan is for testing and development only. For production use of Subdomain Finder, 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 Subdomain Finder from a browser?

Yes! The Subdomain Finder API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.

What happens if I exceed my Subdomain Finder credit limit?

When you reach your monthly credit limit, Subdomain Finder 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.
