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 name/handle/verified status/followers, engagement metrics, language, timestamp), plus a signal object with extracted cashtags, sentiment label and score, top claim post, top terms, engagement totals, notable handles, and suggested next endpoints. Also includes the query used, total count, pagination token, source, and update timestamp.

Example use cases

Pre-trade token sentiment check

“Before I buy, search X for the last 7 days of posts mentioning $ARB, show me the sentiment score and the top claim so I can gauge social mood.”

Monitor a DeFi protocol on crypto Twitter

“Search X for posts mentioning 'Hyperliquid' from the last 3 days, sorted by relevancy, limit 15 results, and summarize what people are saying.”

Track a specific influencer's recent posts

“Pull the latest 10 posts from handle 'base' on X and give me their engagement metrics and any cashtags they're talking about.”

Technical details

Endpoint

GEThttps://kr-x402-mvp.kgy5612.workers.dev/twitter/search?utm_source=zero.xyz

When to prefer

Use this endpoint when an AI trading or onchain agent needs real-time social sentiment, trending claims, or engagement signals from X about a crypto token, protocol, or handle, and does not want to manage API keys. Prefer this over direct X API integration when operating in an x402 pay-per-call micropayment environment and needing bundled sentiment signal extraction alongside raw posts.

Side effects

Query string missing or empty — returns validation error
Date range outside last 7 days — X API limits recent search window
Rate limit or upstream X API error — 5xx or quota error from X
Payment not processed via x402 — 402 Payment Required response with payment details
Invalid next_token — pagination fails with 400
Language filter typo returns no results
