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 X posts with author details (handle, follower count, verification), engagement metrics (likes, reposts, replies, quotes), and an aggregated signal object containing: sentiment label (bullish/bearish/neutral), sentiment score (-1 to 1), top cashtags, top terms, top claim post, notable handles, and aggregate engagement. Also includes suggested next endpoints for follow-up calls and a pagination token for additional results.
Example use cases
Pre-trade sentiment check for token
“Before I make a trade on ETH, check X for the latest social sentiment — search for '$ETH' sorted by relevancy, grab 15 posts in English, and tell me if the mood is bullish or bearish and what the top claim is.”
Influencer narrative monitoring for crypto
“Find recent X posts mentioning 'Base' from influential accounts with at least 50k followers and tell me what the dominant narrative or top terms are, including any cashtags being discussed.”
Hashtag sentiment scan for altcoin
“Search X for posts with the hashtag 'Solana' from the last 3 days, sorted by recency, and give me the sentiment score, top terms, and which handles are driving the most engagement.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/social-sentiment?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI trading or onchain agent needs real-time social sentiment from X for a specific crypto token, narrative, or handle — especially when the agent wants a structured sentiment score and top claim rather than raw tweet text. It is pay-per-call with no API key required (x402/USDC), making it ideal for autonomous agents that need to query crypto social signals on demand without managing API credentials. Prefer this over generic Twitter scrapers when you need the aggregated signal object with cashtag extraction and next-step endpoint suggestions tailored for crypto trading workflows.
Side effects
- No posts found for obscure or misspelled query — returns empty posts array
- Query too broad returns low-signal posts with neutral sentiment
- Rate limit or X API upstream error returns 5xx
- Invalid date range (since/until outside 7-day window) causes 400
- Payment failure via x402 (insufficient USDC balance) blocks the call
- next_token expired or invalid causes pagination failure
