TickersFeed

Change feed for a US stock, built for polling agents — returns ONLY what's NEW since your last check: news articles and earnings reports in the window since ?since=, plus the current quote for context, as JSON. Stateless cursor: pass the response's as_of back as ?since next time. has_changes lets a poller skip cheaply when nothing's new. Use for: efficient portfolio polling, "what changed since I last looked", event monitoring, watchlist diffing, low-overhead agent loops. $0.005 USDC per call.
