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 JSON object with matched posts (id, URL, language, text, author name/handle/verified status/followers, and metrics like likes/quotes/replies/reposts), a signal summary (top cashtags, sentiment label and score, top claim, top terms, engagement totals, notable handles), the query used, a pagination next_token if more results exist, and suggested next API calls. Source and updated_at timestamp are also included.
Example use cases
Crypto sentiment monitoring for a token
“Search X for recent posts with the cashtag $SOL, sorted by relevancy, limit to 10 results in English, and tell me the overall sentiment score and what the top claim is.”
Influencer activity tracking
“Find the latest posts from the handle 'CryptoWhale' on X about Bitcoin, sorted by recency, and show me engagement metrics like likes and reposts.”
Hashtag-based trend detection
“Search X for posts with the hashtag 'DeFi' that have at least 100 likes, from the last 7 days, sorted by relevancy, and give me the top 10 results with sentiment analysis.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/x-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs real-time X/Twitter post data with sentiment and engagement signals for crypto topics, without needing a traditional API key — especially when operating in a pay-per-call micropayment architecture via x402 on Base. Prefer this over scraping tools when structured signal extraction (sentiment score, top cashtags, notable handles) is needed alongside raw posts. It is particularly well-suited for trading agents that need social sentiment as a signal input alongside price or on-chain data from sibling endpoints on the same platform.
Side effects
- Payment failure if USDC balance on Base is insufficient (x402 payment required)
- Empty results if query matches no recent posts within the 7-day window
- Rate limiting or quota exhaustion from underlying X API
- Invalid query syntax causing a 400 error
- Pagination token expiry if too much time passes between paginated requests
- Language filter mismatch returning no posts for rare language+query combinations
