Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.5.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://legalpulse.theaslangroupllc.com/api/legal/sign-check?type=freelance+%7C+lease+%7C+employment+%7C+nda+%7C+saas+%7C+service+%7C+purchase+%7C+...'

# 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://legalpulse.theaslangroupllc.com/api/legal/sign-check?type=freelance+%7C+lease+%7C+employment+%7C+nda+%7C+saas+%7C+service+%7C+purchase+%7C+...' \
