Quickstart

Create an API key

Sign in to the Nadcab Labs Console and open Settings → Key & Access. Create a key and copy it. Keys start with ncl_.Store the key on your server only. See Authentication.

Check your balance

Cards are funded from your account balance.

curl https://cc.nadcab.com/api/v1/account/balance \
  -H "Authorization: Bearer $NADCAB_API_KEY"

To add funds, get a deposit address with Get deposit address and send USDT or USDC to it.

Pick a BIN

List the BINs your account can issue on, with their fees, limits and verification requirements.

curl https://cc.nadcab.com/api/v1/bins \
  -H "Authorization: Bearer $NADCAB_API_KEY"

Create a card

Pass the BIN id or bin, an initial top-up amount, and your own reference in clientTransactionId.

curl https://cc.nadcab.com/api/v1/cards/create \
  -H "Authorization: Bearer $NADCAB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "bin": "111111",
    "amount": "10",
    "clientTransactionId": "order-1001",
    "ipAddress": "203.0.113.10"
  }'

The response returns a transaction ID. Card creation is asynchronous: the card details arrive in a CreateCard webhook.
