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 (id, URL, text, author handle/name/followers/verified, language, created_at, and per-post metrics: likes, reposts, replies, quotes), plus an aggregated signal object containing overall sentiment label (bullish/bearish/neutral), sentiment score, top cashtags mentioned, top terms, top claim post, engagement totals, and notable handles. Also includes a next_token for pagination and suggested follow-up endpoint paths.
Example use cases
Pre-trade sentiment check on a token
“Before I buy $ETH, search X for the most relevant recent posts about Ethereum and tell me whether sentiment is bullish or bearish — include top terms and any notable handles posting about it.”
Monitoring a new token launch buzz
“Search X for posts mentioning the hashtag 'x402' from the last 3 days, sorted by recency, and show me the top 15 posts with their engagement numbers and the overall sentiment signal.”
Tracking posts from a specific crypto influencer
“Pull the latest 10 posts from handle @base on X about crypto and summarize what they've been saying — include likes, replies, and reposts for each.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/crypto/social?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI trading or onchain agent needs real-time social sentiment from X (Twitter) for a specific crypto token, handle, or topic — especially when combined with price or market data from sibling endpoints. Ideal for pre-trade sentiment checks, monitoring token launch buzz, or tracking influential crypto accounts. Prefer this over general web search when you need structured engagement metrics, cashtag extraction, and a ready-made sentiment score rather than raw HTML or unstructured text.
Side effects
- Query too long (>200 chars) returns 400 validation error
- No results found for niche or misspelled query returns empty posts array
- since/until outside the allowed 7-day window returns error or empty results
- Payment failure via x402 (insufficient USDC balance) returns 402 with payment details
- X API rate limits or downtime cause 502/503 errors
- Invalid next_token for pagination returns error or restarts from beginning
