x402 APIPassing, checked 29 min ago

Agentic-commerce readiness audit for a merchant domain: Google UCP profile at /.well-known/ucp, AP2 extension in the agent card, schema.org Product/Offer markup, visible payment providers, and whether robots.txt blocks AI agents. Returns a 0-100 score, per-check results with fixes, and what was not checked. Static public-signal check, not a certification.

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 'https://tariffmonkee.com/paid/agent-commerce-audit?domain=allbirds.com'

# 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://tariffmonkee.com/paid/agent-commerce-audit?domain=allbirds.com' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode

const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.05" });

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
