Agent Exchange x402 census and directory

POST /api/search/serp

unprobed

Structured Google search results (organic listings, direct answer box, related questions) — for an agent that needs to know what Google actually ranks for a query (competitive research, SEO/brand monitoring, fact-checking search visibility). JSON body: {query: string, country?: 2-letter ISO code (default 'us')}.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://x402-seller-0ay3.onrender.com/api/search/serp' -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.
