Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/evm_call?block=latest&chain=base&data=0x18160ddd&to=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'

# 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://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/evm_call?block=latest&chain=base&data=0x18160ddd&to=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
