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://api.manylives.me/paid/tx/explain?tx=0xb33254bb0332ea6bede020e6f2aa4df0161e0e5b6ce9559b56859ce32c1ec163'

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