Fetch the transcript of any YouTube video. Pulls auto-generated or manual captions and returns full text plus per-segment {start, duration, text}, with an optional language pick. Backed by Supadata's transcript pipeline server-side — no caller key required; returns a clear 404 when a video has no transcript. Use it as a YouTube closed-caption fetcher or video subtitles puller.

AgentUtility.ai · Stocks News
x402.agentutility.ai
Fetches recent stock market news on equities, earnings, IPOs, the Fed, and macro from GDELT with a GNews fallback when configured, returning headline metadata with sentiment and source domains. The equities companion to crypto-news. Data-only news digests; no price prediction, trading advice, or order routing. Use it as a stocks news API, equities news feed, earnings news source, or Wall Street headlines for agents.
AgentUtility.ai · Search Site
x402.agentutility.ai
Site/domain-scoped search via Decodo Google results. If primary search is quota-limited, a best-effort fallback maps site: to GDELT domain: and returns marked degraded recent public-news results (https://www.gdeltproject.org/); fallback recency is capped at 168 hours and only news-indexed pages can appear. Use it as a domain-search API for agents.
AgentUtility.ai · Recent Tweet Search
x402.agentutility.ai
Repeat a saved recent-tweet search to monitor a brand, topic, or phrase over time. Send the same query, language, and max_results on each check; it returns recent public post text, timestamps, metrics, and expanded author profiles. If native X search cannot answer, the tweets array contains clearly labeled public-index results with degraded: true instead of an empty paid response. Read-only: no posting, replying, liking, following, or direct-message access. Use it as a recent tweet search API, Twitter monitoring API, saved-query watchlist, or X public-post search.
