Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.008.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agents.citiviewgroup.com/v1/sanctions?address=0x0330070FD38Ec3bB94F58FA55D40368271E9e54A'

# 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://agents.citiviewgroup.com/v1/sanctions?address=0x0330070FD38Ec3bB94F58FA55D40368271E9e54A' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
