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 'https://saylorinnovations.com/api/useragent/parse?ua=Mozilla%2F5.0+%28iPhone%3B+CPU+iPhone+OS+17_5+like+Mac+OS+X%29+AppleWebKit%2F605.1.15+%28KHTML%2C+like+Gecko%29+Version%2F17.5+Mobile%2F15E148+Safari%2F604.1'

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