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://video-calc.x402tookit.com/timecode-math?a=01%3A00%3A00%3A00&b=00%3A00%3A30%3A12&fps=25&op=add'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://video-calc.x402tookit.com/timecode-math?a=01%3A00%3A00%3A00&b=00%3A00%3A30%3A12&fps=25&op=add' \
