Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.03.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.manylives.me/paid/trackrecord/correlate?ids=CRY-5m-001%2CCRY-5m-002%2CCRY-5m-003&window=7d'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:

  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
