GET /search/advanced

unprobed

Deep web research for AI agents — advanced search returning the highest-relevance results with multiple query-focused snippets per source, plus an optional LLM-generated answer grounded in the returned sources when include_answer is set. One-call research assistant for high-precision queries; news and finance topics, date and domain filters.

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 GET 'https://websearch.use.x402atlas.com/search/advanced' -H 'accept: application/json'

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.
