# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://api.cn402.com/tcm/constitution?answers=Answers (optional)&mode=Operation mode (optional)"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
