Buy crypto with fiat

Goal

Generate a MoonPay checkout URL for buying crypto with a credit card or bank transfer. The user completes the purchase in their browser.

Command

mp buy \
  --token <currency-code> \
  --amount <usd-amount> \
  --wallet <destination-address> \
  --email <buyer-email>

Supported tokens

btc, sol, eth, trx, pol_polygon, usdc, usdc_sol, usdc_base, usdc_arbitrum, usdc_optimism, usdc_polygon, usdt_trx, eth_polygon, eth_optimism, eth_base, eth_arbitrum

Example flow

1. User: "I want to buy $50 of SOL with my credit card."
2. Run: mp buy --token sol --amount 50 --wallet <address> --email user@example.com
3. Open the returned checkout URL in the user's browser so they can complete the purchase.

Notes

• This is fiat-to-crypto (credit card / bank), not a token swap.
• For token-to-token swaps, use the moonpay-swap-tokens skill instead.
• The --amount flag is in USD (e.g. --amount 50 = $50 worth of the token).
• The --token flag uses MoonPay currency codes, not mint addresses.
• The checkout URL handles KYC and payment processing.
