Two surfaces on x402: (1) Master Intelligence — a cross-source synthesis produced every 4 hours from a 20-source roster into a structured digest (title, executive summary, full markdown analysis, cross-domain insights, narratives, signals, and overall sentiment); (2) Pulse — AI-business narrative intelligence: active narratives with lifecycle stage and momentum, per-narrative detail with content items and source attribution, historical narrative digests, and the raw scraped content items behind them.
