Card Generator is a simple tool for generating test/sample card numbers. It returns a list of card numbers for testing.

The Card Generator API provides reliable and fast access to card generator data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.

To use Card Generator, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA

Access Card Generator through GraphQL to combine it with other API calls in a single request. Query only the card generator data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Card Generator 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 {
  cardgenerator(
    input: {
      brand: "visa"
      count: 5
    }
  ) {
    brand
    count
    cards
    owner {
      name
      address {
        street
        city
        state
        zipCode
      }
    }
  }
}

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

CORS Support

The Card Generator API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Card Generator 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 Card Generator directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

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

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

Frequently Asked Questions

How do I get an API key for Card Generator?
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 Card Generator and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
How many credits does Card Generator cost?

Each successful Card Generator 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 card generator lookups.

Can I use Card Generator in production?

The free plan is for testing and development only. For production use of Card Generator, 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 Card Generator from a browser?
Yes! The Card Generator 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 Card Generator credit limit?

When you reach your monthly credit limit, Card Generator 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.
