Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://opendata402.com/v1/nl/statutory-interest?amount=1000&from=2024-03-01&to=2026-10-14&type=commercial'

# 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://opendata402.com/v1/nl/statutory-interest?amount=1000&from=2024-03-01&to=2026-10-14&type=commercial' \
