Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.012.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agentrxi.com/v1/media/extract-audio?to=mp3&url=https%3A%2F%2Fagentrxi.com%2Fsamples%2Fsample.mp4'

# 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://agentrxi.com/v1/media/extract-audio?to=mp3&url=https%3A%2F%2Fagentrxi.com%2Fsamples%2Fsample.mp4' \
