Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.001942.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://plainchain.appin60.com/v1/balances?address=0xB442daCAE60C07bb5dB8f33C8a6c1572d8F24e83&chain=base'

# 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://plainchain.appin60.com/v1/balances?address=0xB442daCAE60C07bb5dB8f33C8a6c1572d8F24e83&chain=base' \
