Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.025.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://agentstoolshub.com/api/v1/nft/collection-due-diligence?chain=ethereum&contract=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D'

# 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://agentstoolshub.com/api/v1/nft/collection-due-diligence?chain=ethereum&contract=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D' \
