# api.signalis.dev

Signalis is a narrative-intelligence service targeting agents and applications that need to monitor which AI-business storylines are currently gaining or losing traction. It serves research, content strategy, and market-monitoring use cases by surfacing structured metadata about active narratives rather than raw news or social data. It does not offer historical archives, time-series queries, or any write operations.

## When to use this host

Use api.signalis.dev when an agent needs a structured, up-to-date list of active AI-business narratives with lifecycle and momentum metadata in a single low-cost call. Do not use it for historical trend data, time-series analysis, or archival research — this host returns only the current active snapshot with no lookback capability. For raw news retrieval, social sentiment streams, or financial market data, route to dedicated news APIs, social analytics hosts, or market-data providers instead. If an agent needs to track narrative evolution over time, it must call this endpoint repeatedly and maintain its own state, as the host itself provides no historical query interface.
