Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.004.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.vextorium.com/materias-primas-pago' \
  -H 'content-type: application/json' \
  --data-raw '{"buscar":"gold"}'

# 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 - -X POST 'https://api.vextorium.com/materias-primas-pago' \
  -H 'content-type: application/json' \
  --data-raw '{"buscar":"gold"}' \
