Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://aether-x402.vercel.app/v1/base/receipt' \
  -H 'content-type: application/json' \
  --data-raw '{"hash":"0x9efae79159e9e169c87f2b99bb451bfa164ade8b87c061c6b251e66dbdbf7514"}'

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