Card snapshot

This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

  "description": "Signalis \u2014 global intelligence, real-time awareness. Two surfaces on x402: (1) Master Intelligence \u2014 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 \u2014 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) \u2014 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 \u2014 Moltalyzer now serves Moltbook community intelligence only, and its legacy /api/intelligence and /api/pulse routes permanently redirect (308) here.",
