Issue virtual crypto-funded cards and manage payments programmatically using the Aurex API.

Setup

Get your API key at aurex.cash → Dashboard → API Keys.

export AUREX_API_KEY="your-api-key"

Base URL: https://aurex.cash/api/dashboard Auth: Authorization: Bearer $AUREX_API_KEY Rate limit: 60 requests/minute

Security

• Store AUREX_API_KEY in environment variables only — never hardcode or log it
• Card details (number, CVV, expiry, OTP) are sensitive — never log or store them in plaintext
• Only request card details when strictly necessary for the user's task
• Treat CVV and OTP as single-use secrets — discard after use
