Credits System

Overview

Ender uses a simple, transparent credit-based pricing system. You only pay for what you use, and credits are consumed only when API calls succeed.

Credit Priority

When you make API calls, credits are consumed in this order:

1. Plan Credits (from your subscription) are used first
2. Balance Credits (from top-ups) are used when plan credits run out

Credit Costs by Module

Card Checkers

Credits are charged based on the check result:

Credit Calculation Examples

Example 1: Auth Check with System Proxy

Check: Auth (Stripe)
Result: Live
Proxy: System (not provided)

Cost = 3 (live) + 1 (system proxy) = 4 credits

Example 2: Shopify Check with User Proxy

Check: Shopify
Result: Charged
Proxy: User provided

Cost = 5 (charged) = 5 credits

Example 3: Dead Card Check

Check: Charge
Result: Dead
Proxy: System (not provided)

Cost = 1 credit (dead cards don't incur system proxy cost)

Example 4: CC Killer

Tool: CC Killer
Cards: Up to 100 per batch

Cost = 80 credits per batch (flat rate)

  -H "Content-Type: application/json"

Cost Optimization Tips

1. Use Your Own Proxies

Providing your own proxy saves 1 credit per approved/live check:

{
  "gate": "stripe",
  "cc": "4111111111111111|12|25|123",
  "proxy": "http://user:pass@ip:port"
}

2. Pre-validate Data

Clean and validate your card data before submitting to reduce dead card checks.

3. Handle Errors Properly

Errors don't cost credits, so implement proper error handling and retry logic.

Gifting Credits

You can gift credits to other users using coupons:

curl -X POST https://api.ender.black/v1/coupons/create \
  -H "Authorization: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "credits": 1000,
    "message": "Enjoy!",
    "expirationDays": 30
  }'

FAQ

Do errors cost credits?

No! If an API call results in an error (network issues, invalid request, etc.), no credits are charged.

Can I transfer credits between accounts?

Yes, you can create credit coupons to gift credits to other users.

Do unused plan credits roll over?

No, plan credits expire at the end of your billing period. Balance credits (from top-ups) never expire.

What happens when I run out of credits?

API calls will return an error indicating insufficient credits. Top up your balance to continue.
