How this service works
Use when an agent, x402 test or CI job needs Base Sepolia gas now: one x402 call, no faucet login or mainnet history. Input: to (recipient address); sends 0.1 ETH (1 ETH: /v1/testnet/base-sepolia-eth/1). 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
Output
A JSON object containing the confirmed on-chain transaction hash (txHash), a block explorer URL (explorerUrl), the amount sent in ETH and Wei (amountEth, amountWei), the sender address (from), the recipient address (to), block number, chain ID, network name, nonce, status, and any advisory notes — all confirmed before settlement.
Example use cases
CI pipeline gas top-up
“My CI job deploys to Base Sepolia and keeps running out of gas — send 0.1 ETH to 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234 so the deployment tests can run.”
Agent wallet bootstrap
“My AI agent's wallet at 0xDEAD000000000000000042069000000000000000 has no Base Sepolia ETH and can't pay for transactions — top it up with 0.1 ETH right now.”
x402 integration testing
“I'm testing an x402 payment flow and need my test address 0xBEEF000000000000000000000000000000001234 funded with Base Sepolia ETH — can you send 0.1 ETH to it?”

Choose this endpoint when you need Base Sepolia testnet ETH instantly via a programmatic x402 call — no faucet UI, no mainnet history required, no login. Ideal for CI pipelines, automated agent wallets, or x402 integration tests where 0.1 ETH per call is sufficient. For 1 ETH per call, use the /v1/testnet/base-sepolia-eth/1 sibling endpoint. Not suitable for mainnet ETH or non-Base-Sepolia networks.
