How this service works
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.
Output
Returns a JSON object containing: an array of posts (each with id, url, text, createdAt, lang, author object with handle/name/id, engagement metrics, hashtags, outbound links, and mentions), a newestId string to use as sinceId on the next poll, a complete flag indicating whether all results were returned, the query parameters used, and a polledAt timestamp.
Example use cases
Crypto influencer feed for trading agent
“Monitor these 10 crypto KOLs — @elonmusk, @VitalikButerin, @cz_binance, @aantonop, @balajis, @naval, @APompliano, @RaoulGMI, @CathieDWood, @novogratz — for any new English posts with at least 100 likes, filter out airdrop and giveaway spam, and pick up from tweet ID 1799000000000000000 so we don't re-process anything.”
Newsletter curation from thought leaders
“Pull the latest posts from @paulg, @naval, @pmarca, @benedictevans, and @stratechery since post ID 1801000000000000000, only in English, with a minimum of 20 likes, and skip any spam — I want to curate the best new ideas for my weekly newsletter.”
Hourly KOL alert bot for a Telegram channel
“Every hour, check @DegenerateNews, @AltcoinSherpa, @Pentosh1, @CryptoCapo_, and @IncomeSharks for new English tweets with at least 10 likes since the last newestId I give you, and filter out all airdrop and presale bait — I'll push the results to my Telegram alert channel.”
Technical details
Endpoint
GEThttps://x402.botsmith.dev/x/watchlist?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to monitor multiple X accounts (up to 15) in a single call with built-in spam filtering, engagement thresholds, and incremental cursor support — eliminating the need to build your own search, deduplication, retweet filtering, and paging logic. Prefer it over raw X API or search endpoints when you want a zero-setup KOL monitoring loop that requires no X account or API key, and when crypto spam filtering is important. Use the sibling X Tweet Search endpoint instead if you need arbitrary advanced-search query syntax beyond a fixed handle list.
Side effects
- Invalid handles format returns validation error — handles must be comma-separated, 1-15 accounts, valid X handle format

- Language code not a valid two-letter ISO code returns error
- minFaves out of range (above 100000) returns validation error
- All posts filtered out by spam or engagement floor returns empty posts array with valid newestId
- X/Twitter upstream unavailability causes fetch failure
- Payment not completed results in 402 response before data is returned
