Use when contract deploys, x402 tests or CI jobs need more Base Sepolia gas than a faucet gives: one x402 call, no faucet login or mainnet history. Input: to (recipient address); sends 1 Base Sepolia ETH. Output: JSON txHash (confirmed before settling), explorerUrl, amountEth, from, to. Daily limits (UTC): 5 ETH per address (both sizes), 20 overall; checked before payment. Test ETH has no monetary value. Example: ?to=0x000000000000000000000000000000000000dEaD
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
