The gateway plans sub-questions, runs multiple live web searches, reranks the sources by relevance, and synthesizes a ~1,500-word report with inline [n] citations and a source list - one payment, one outcome. Priced per report, not per call. Payable in USDC (x402/MPP) or by card (Stripe, >= $0.50 minimum - this clears it).

Prefer it over raw search APIs when synthesis and citation quality matter, and over general LLM prompting when up-to-date sourced information is required. The pay-per-call, no-API-key model makes it ideal for agentic pipelines that need on-demand research without subscription overhead.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-15T13:06:50.058Z","isFirstParty":false}
