About Marginal

Track every LLM call's cost and slice it by customer, feature, model, any field you define. Marginal tracks the cost of every LLM call and slices it by the fields you care about, customer, feature, model. Cost is computed server-side, usage in, dollars out. Every API request is logged with its outcome, accepted counts, rejected events and why, stripped keys, unpriced models. The SDKs are zero-dependency, buffered, fire-and-forget: track() never throws and never blocks your request path.

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.
