GET https://x402.ottoai.services/tweet-search ↗

Search X/Twitter for any query and get the actual matching tweets — keyword, $CASHTAG, from:handle (a user timeline), @handle (mentions), or boolean OR. Each tweet returns author, full text (long-form note tweets included), timestamp, likes and retweets (reply/quote counts when available). Most-recent-first for real-time monitoring and alerting. Live X search backend, pay-per-call USDC, structured JSON — no API keys, no sign-up.
