GET /api/buy/research_comparison
unprobed
Research Comparison. REQUIRES ?urls= on the paid request — a signed request without it is refused before the gate and no money moves. One signed comparison: live atomic payment terms, dated host history and gaps, same-endpoint network changes, shared receivers and limits. No research quality or ownership verdict. Full listing: https://scvd.store/menu/research_comparison. MCP tool: buy_research_co…
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
