X KOL Watchlist Monitor ($0.05/call): Watch up to 15 X (Twitter) accounts with one call: every new post from the list since your last poll, above your engagement floor, with retweets and crypto-spam (airdrop/giveaway/presale bait) filtered out and duplicates removed. Pass the returned newestId back as sinceId to get only what is new - replaces the search + filter + dedupe + paging loop KOL-monitoring agents build by hand. No X account or API key needed.
