Card Checkers

Overview

Ender's Card Checker modules validate credit cards against various payment gateways. Each checker is optimized for specific use cases and provides detailed response information.

Available Checkers

Credit Costs

Response Status Mapping

All checkers follow a consistent response pattern:

Common Request Parameters

All checker endpoints accept these common parameters:

Proxy Formats

Ender supports multiple proxy formats:

http://ip:port
http://user:pass@ip:port
socks5://ip:port
socks5://user:pass@ip:port
ip:port:user:pass

Best Practices

1. Use your own proxies — Save 1 credit per check
2. Validate card format — Avoid unnecessary API calls
3. Handle all status types — Build robust error handling
4. Implement retry logic — Errors don't cost credits
5. Rotate proxies — Avoid blocks and improve success rates

Quick Example

const response = await fetch("https://api.ender.black/v1/checkers/auth", {
  method: "POST",
  headers: {
    Authorization: "YOUR_API_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    gate: "stripe",
    cc: "4111111111111111|12|25|123",
    proxy: "http://user:pass@ip:port",
  }),
});
 
const data = await response.json();
 
if (data.success) {
  if (data.data.auth) {
    console.log("Card approved!");
  } else if (data.data.live) {
    console.log("Card is live");
  } else {
    console.log("Card is dead");
  }
}
