Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://json-data-tools.x402tookit.com/json-format?indent=2&json=%7B%22b%22%3A1%2C%22a%22%3A%5B1%2C2%5D%7D&sort=true'

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