Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.05.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://walcert.globalscoreagent.com/v1/certificates/multichain' \
  -H 'content-type: application/json' \
  --data-raw '{"wallet_address":"0x2eFC66c0a78620Dd254443998BF2f11B685602E3"}'

# 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://walcert.globalscoreagent.com/v1/certificates/multichain' \

  --data-raw '{"wallet_address":"0x2eFC66c0a78620Dd254443998BF2f11B685602E3"}' \
