Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://apexfaucet.xyz/api/x402/evm-balances-bulk?addresses=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045%2C0x024b82335C29Fa5606a8ea5c1D24FC9eAD50700C&chain=base&token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
