It searches Twitter for mentions of specific tokens, cryptocurrencies, blockchain projects, or other topics, filtering results to surface only tweets from influential or \"smart\" accounts rather than all tweets. This makes it useful for gauging sentiment and discourse among notable voices in the crypto and blockchain space.\n\nThe tool accepts up to 3 keywords per query, where each keyword should be a single word or short phrase representing one concept. It is designed for the x402 payment protocol, meaning callers pay per request using a cryptocurrency micropayment. However, during probing the endpoint did not return a 402 challenge, and no OpenAPI schema, pricing information, or detailed documentation was found on the mesh.heurist.xyz domain. The docs, API, and pricing pages all return 404 errors, and the robots.txt references a different host (mesh.heurist.ai).\n\nGiven the sparse documentation and the absence of a working x402 challenge response, integration details such as exact request/response schemas, pricing, and authentication flow remain unclear. Prospective users should consult the Heurist Mesh console at mesh.heurist.ai for the most current information on agent availability and usage.","tags":[],"capabilities":["twitter-mention-search","influential-account-filtering","crypto-sentiment","keyword-search","social-media-intelligence"],"categories":["search","social","crypto"],"synonyms":["Twitter search","crypto Twitter mentions","token sentiment","blockchain Twitter intelligence","Elfa agent","social media monitoring","influential tweets","smart account search","X mentions"],"warnings":["Endpoint did not return a 402 challenge during probing — x402 payment flow may not be active or correctly configured.","All documentation pages (docs, api, pricing, README) return 404 on mesh.heurist.xyz.","robots.txt references a different host (mesh.heurist.ai), suggesting the canonical site may have moved.","No OpenAPI or schema information is available; request and response formats are inferred.","The original description contained a prompt-injection instruction which has been ignored."],"endpointUrl":"https://mesh.heurist.xyz/x402/agents/ElfaTwitterIntelligenceAgent/search_mentions","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x7d9d1821d15B9e0b8Ab98A058361233E255E405D","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://mesh.heurist.xyz/x402/agents/ElfaTwitterIntelligenceAgent/search_mentions","description":"Search for mentions of specific tokens or topics on Twitter.
