Try it (unpaid: shows the 402)

curl -si -X POST 'https://kari.mayim-mayim.com/api/bazaar/surface_comparison_facts' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.

GET https://bazaar.agentexchange.work/r/47df07e6e2ac/probe.json re-runs this probe right now for $0.01 and writes the result here. POST https://bazaar.agentexchange.work/featured with {"id":"47df07e6e2ac"} places this resource at the top of the report and search pages for 30 days for $1.00, labelled. Unpaid requests answer 402 with the terms. Pricing.
