POST /deep

unprobed

Search Aggregator deep tier: Tavily+Exa+Firecrawl merged results with full page content and synthesized answer, fixed price $0.05 USDC. POST JSON body {query (required), max_results (optional 1-20, default 10)}. Mode is fixed by the path — no mode field needed, the quoted price is always the settled price.

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 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.
