GET /v1/probers
unprobed
Census of automated x402 monitors and index crawlers observed polling a Bazaar listing on Base mainnet: user-agent prefix, operator URL, stated purpose, class (monitor or crawler), quotes served in the observation week. Updated weekly from live terminal logs.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares GET. 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.
