About Sidereon

One reference-validated GNSS and astrodynamics engine. A Rust core with first-class interfaces in Rust, Go, Python, C, Elixir, and WebAssembly. Everything below is the same core compiled to WebAssembly, executing client-side in this tab. Fixes arrive with covariances; wide-covariance fixes get almost no weight, so spikes cannot pull the track. Parsed, differenced, floated epoch by epoch (the teal path is the float estimate converging on truth), then wide-lane fixed by the WASM engine in this tab.

About Stock News API

REST API for relevance-scored, ticker-linked financial news: a real-time stock news API for trading bots, AI agents, and dashboards. Free tier, no credit card. Every article arrives scored for relevance and linked to tickers, so a trading bot or an agent backend can filter the wire at request time. Filter server-side Symbol, category, minimum relevance and delta polling are query params, so the wire is cut before it costs you a token. Enough to evaluate the feed and build a prototype.
