By sending a natural-language prompt in the `input` field along with an x402 payment header, callers can instruct the agent to perform Twitter actions such as composing and posting tweets, searching or querying a user's latest tweets, retrieving tweet details, and subscribing to new tweets from specific users or curated tweet lists.\n\nPayment is handled on the Base Sepolia testnet using USDC (asset `0x036CbD53842c5426634e7929541eC2318f3dCF7e`) with a maximum charge of 100,000 units per request and a timeout of up to 1,200 seconds. The agent accepts a single POST body field (`input`: string) and returns a single `response` string. No OpenAPI spec or detailed documentation is available beyond the x402 challenge metadata and the agent's short description.\n\nThe underlying platform is Questflow, which markets itself as an AI-agent economy focused on onchain markets and autonomous trading clones. This particular agent is narrowly scoped to Twitter interactions. Because the endpoint is on a `-dev` subdomain and uses a testnet for payments, it should be treated as a development/staging service rather than a production-grade API.","tags":[],"capabilities":["tweet-posting","tweet-search","tweet-detail-retrieval","twitter-user-monitoring","tweet-list-listening","natural-language-input","x402-payment"],"categories":["social-media","automation"],"synonyms":["Twitter API agent","X posting bot","tweet search agent","Twitter automation","social media agent","tweet listener","Questflow Twitter"],"warnings":["Endpoint is on a development subdomain (api-dev) and uses Base Sepolia testnet — not suitable for production use.","No OpenAPI specification or detailed API documentation is available.","The example response is inferred; actual response format is unverified.","maxAmountRequired of 100,000 units — denomination/decimals unclear without confirming USDC decimals on Sepolia.","Agent capabilities (tweet posting, listening) are described only in a short blurb; actual feature coverage is unverified."],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68230442d973977d61d66ccb","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x36e547e18236e8cc2B01CfD735bdB2705E6D4E99","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:68230442d973977d61d66ccb","description":"Twitter agent enables users to post and interact with messages known as \"tweets.\" Can write a tweet, listen to twitter user post new tweet, query or search user latest tweets, get tweet detail, listen to a special tweet list. | Powered by Questflow","outputSchema":{"input":{"type":"http","method":"POST","bodyFields":{"input":{"type":"string","required":true,"description":"Your message to the agent"}},"discoverable":true},"output":{"response":{"type":"string","required":true,"description":"Response from the agent"}}},"maxAmountRequired":"100000","maxTimeoutSeconds":1200}]},"qualityScore":"0.300","qualityRationale":"No OpenAPI spec, no dedicated documentation, no usage examples, and the endpoint is on a dev subdomain using testnet payments.
