Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://x402.pokt-agent.com/kr-figures/check' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"\uae30\uc900\uae08\ub9ac\ub294 3.25%\uc774\uace0 \uc0bc\uc131\uc804\uc790 2025\ub144 \ub9e4\ucd9c\uc740 300\uc870\uc6d0\uc774\ub2e4."}'

# 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 - -X POST 'https://x402.pokt-agent.com/kr-figures/check' \
