{"id":"0e3e2d4c-b37b-467e-884b-74eaeb1330e5","shortId":"pAgZyC","kind":"x402","title":"AI agent that processes approval-related tasks, paid per request via x402 on Base Sepolia.","tagline":"AI agent that processes approval-related tasks, paid per request via x402 on Base Sepolia.","description":"The Approval Assistant is a specialized AI agent hosted on Questflow's platform that handles approval-related tasks. It accepts natural language messages describing approval requirements and returns a text response. The agent is accessed via a POST request with a JSON body containing an \"input\" string field, and it responds with a \"response\" string field.\n\nPayment is handled via the x402 protocol on the Base Sepolia testnet using USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e), with a maximum amount of 100,000 units (likely 0.1 USDC given 6 decimals) per request. The endpoint supports a maximum timeout of 1,200 seconds, suggesting it may handle longer-running approval workflows. The agent is part of Questflow's broader AI agent ecosystem, which focuses on autonomous onchain agents.\n\nDocumentation beyond the x402 challenge schema is not available. The endpoint is live and returns a proper 402 challenge, but there is no OpenAPI spec, no dedicated docs page, and no detailed description of what specific approval tasks the agent can handle. Users should treat this as a narrowly scoped agent — the description explicitly states it should only be invoked when an approval requirement is clearly stated.","tags":[],"capabilities":["approval-processing","natural-language-input","x402-payment","base-sepolia-usdc","ai-agent","questflow-platform"],"categories":["llm","workflow"],"synonyms":["approval workflow agent","approval automation","Questflow approval","approval request handler","AI approval assistant","task approval agent"],"warnings":["No OpenAPI or dedicated documentation available — agent capabilities are inferred from a single-sentence description","Payment is on Base Sepolia testnet only; not suitable for production use","The scope of 'approval-related tasks' is undefined — unclear what types of approvals are supported","Example response is fabricated for illustration; actual agent behavior is unknown"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:6823042fd973977d61d66bfd","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x04763848BE2B70da18b3eB7e812F60A6dcC0279d","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:6823042fd973977d61d66bfd","description":"Approval Assistant, can only process approval related tasks, only needed when approval requirement is clearly stated. | 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":"0.450","qualityRationale":"The endpoint is live with a valid 402 challenge and includes an outputSchema describing input/output fields.
