{"id":"04c2aef9-fd1d-4c5c-8eed-3bab05872a71","shortId":"fxGSeR","kind":"x402","title":"Pay-per-call Twitter agent: post tweets, search timelines, and monitor accounts via x402 on Base.","tagline":"Pay-per-call Twitter agent: post tweets, search timelines, and monitor accounts via x402 on Base.","description":"This Questflow-hosted Twitter agent exposes common Twitter/X operations—posting tweets, searching a user's latest tweets, retrieving tweet details, and listening for new posts from specific accounts or tweet lists—through a single x402-payable HTTP POST endpoint. The agent accepts a natural-language prompt in the `input` field and returns a text `response`.\n\nPayment is handled via the x402 protocol on the Base network using USDC (contract 0x8335…2913). The maximum amount required per call is 100,000 units (likely 0.10 USDC given 6-decimal USDC), with a maximum timeout of 1,200 seconds. The endpoint is discoverable and returns `application/json`.\n\nDocumentation is minimal: there is no OpenAPI spec, no dedicated docs page, and no public pricing page beyond what the x402 challenge header reveals. The agent is part of Questflow's broader AI-agent platform, which focuses on autonomous onchain trading clones, but this particular agent is scoped to Twitter interactions only. Because the endpoint schema is simple (one string in, one string out) and no further documentation exists, callers should experiment with prompt phrasing to discover the full range of supported Twitter actions.","tags":[],"capabilities":["tweet-posting","tweet-search","tweet-detail-retrieval","twitter-user-monitoring","tweet-list-monitoring","natural-language-input","x402-payment","usdc-base-payment"],"categories":["social-media","automation"],"synonyms":["Twitter API agent","X posting bot","tweet search agent","Twitter automation","Questflow Twitter","tweet monitoring","social media agent","x402 Twitter"],"warnings":["No OpenAPI or dedicated API documentation available","Output schema is a single unstructured string; no structured tweet objects","Example response is fabricated/inferred—actual format unknown","No rate-limit or quota information disclosed","maxAmountRequired of 100000 units—actual USDC cost unclear (likely 0.10 USDC with 6 decimals, but unconfirmed)","Platform primarily markets AI trading clones; this Twitter agent's maintenance status is unclear"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:687df7dbb234010b7d331d0c","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0xeF98feeb67420dcdb5EAaADaE27f168Fe534Ac29","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:687df7dbb234010b7d331d0c","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":"0.350","qualityRationale":"The x402 challenge provides a basic input/output schema and payment details, but there is no OpenAPI spec, no docs page, no usage examples, and no detailed capability documentation.
