POST /tools/search
unprobed
Full-text search across every aggregated data source in one call: news, SEC filings, court opinions, academic papers, government records, and developer discussions. One query surfaces everything concordant across independently-sourced, citable results -- not a single-source wrapper. Optional source/category/since filters.
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.
