Signal API

Services & APIs

Signal API is an events-first API: prediction-venue and RSS-clustered events on /v1/events, LLM-synthesized articles grounded on those clusters, plus market catalogs and proposals. We also build custom ingestion and endpoints.

Under the hood

Ingestion (RSS, venues), clustering, scoring, fact extraction, and LLM synthesis on event clusters. Events and news share cluster IDs—events-first reads, separate news routes. One engine, one graph.

Events API

Primary feed: clustered RSS signals and optional Polymarket/Kalshi rows as events. Latest, trending, by country and category. Deterministic reads—built for prediction markets and B2B analytics.

Eventa API

Multilingual curated global feeds (when enabled on the deployment), the same clustered /v1/events surface as Live, and GET /v1/eventa/proposals with rich filters for prediction-style hypotheses.

Synthesized News API

LLM articles from facts tied to the same event clusters as /v1/events. Multi-language, anti-plagiarism, human-in-the-loop.

Full details →

Markets API

Venue catalogs and review-only proposals; many instruments also surface as events. Submit from LLM workers with human review. For prediction platforms.
