Share this result
Every ARC page and dataset is free to read, cite and reuse.
OpenClaw only follows labelled controls. A block at the door is one result for all five, with the HTTP evidence. The score is the ARC browser cart, the same number as a free scan. The agent-catalog check above is real and leads the buy verdict. It does not change the score. How it works.
BADGE FOR YOUR SITE
Put this on your site. It links back here. It says Agent checkout when the real catalog check returned a checkout link, and Agents chose us only when a browser cart shopper added the product to the cart.
