What the listing says

Determine whether a previously accepted x402 service payment contract is still equivalent enough to proceed. Compares one live unpaid 402 challenge, using a caller-supplied GET or POST request shape, against a caller-held baseline bound to that request identity. Not uptime monitoring, a trust score, a webhook, a marketplace crawl, or a generic POST {} probe of every x402 resource.
