by Testnet faucet (try x402 free)
$0.001
per call · USD Coin on Base
Fund any address with testnet money via the Coinbase faucet - USDC (1) or ETH (0.0001) on Base Sepolia, USDC (1) or SOL on Solana devnet - everything an agent needs to rehearse the complete x402 payment loop safely before moving real money. A tenth of a cent buys a full testnet dollar. Limits: 2 drips per address per day; CDP enforces its own rolling caps on top.
