How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
Returns a list of matching posts (id, URL, text, author handle/followers/verified status, engagement metrics), plus an aggregated signal object containing detected cashtags, bullish/bearish sentiment label, sentiment score, top claim post, top terms, engagement totals, and notable handles. Also includes a next_token for pagination and suggested follow-on endpoint paths.
Example use cases
Token sentiment before a trade
“Search X for tweets about $SOL from the last 3 days sorted by relevancy — what's the overall sentiment and what's the most-cited claim right now?”
Influencer timeline monitoring
“Pull the last 10 posts from handle @0xfootrader and tell me the engagement numbers and any cashtags they mentioned.”
Hashtag trend scan for new token
“Find recent X posts with the hashtag #BaseEcosystem, at least 50 likes, in English, sorted by recency — give me the top terms and sentiment score.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/x/tweets/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI trading or onchain agent needs real-time social signal data from X without managing API keys, and is already operating in an x402/USDC payment context. It is especially useful when you need both raw posts AND a pre-computed sentiment/signal summary in a single call, or when you need cashtag-aware search with engagement filtering that goes beyond simple keyword matching.
Side effects
- Payment not included or insufficient USDC — 402 response requiring x402 payment header
- Query string too long or malformed — 400 validation error
- since/until dates outside the 7-day recent-search window — empty or error result
- Rate limits on underlying X API v2 — 429 or degraded results
- No posts match the query — returns n:0 with empty posts array
- Invalid next_token for pagination — may return error or restart from page 1
