  "description": "Signalis — global intelligence, real-time awareness. 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. Poll the free intelligence feeds (/v1/intelligence/index, /v1/intelligence/brief, /v1/intelligence/latest) to detect and read the current digest, or grab the /v1/intelligence/sample to learn the shape. Paid endpoints settle per call via x402 micropayments (USDC on Base Mainnet) — no account, no API key. Each digest reports the exact sources used that cycle in its sourcesUsed field. Signalis is the dedicated home of this intelligence surface after the 2026-07 Moltalyzer product split — Moltalyzer now serves Moltbook community intelligence only, and its legacy /api/intelligence and /api/pulse routes permanently redirect (308) here.",
