The agent accepts natural-language instructions via a simple POST request with an `input` field and returns a text response. Payment is handled through the x402 protocol on the Base network using USDC (max 0.10 USDC per request, asset contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).\n\nQuestflow is a platform that lets users create autonomous AI \"Clones\" that aggregate onchain markets (Polymarket, Pump.fun, OKX, etc.) and execute trades. This particular agent is focused on Aster DEX perpetual trading, supporting both Simple and Pro modes. The endpoint is non-custodial according to its description. The agent has a maximum timeout of 1200 seconds per request, suggesting it may perform on-chain operations or complex reasoning before responding.\n\nDocumentation is minimal — there is no OpenAPI spec, no dedicated docs page, and no detailed API reference beyond the x402 challenge metadata. The input/output schema is straightforward: send a JSON body with an `input` string and receive a `response` string. Pricing is denominated in USDC on Base with a maximum of 0.10 USDC per call.","tags":[],"capabilities":["perpetual-trading","aster-dex","natural-language-input","x402-payment","base-network","usdc-payment","non-custodial","ai-agent","onchain-execution"],"categories":["defi","trading","crypto"],"synonyms":["perps trading agent","Aster DEX API","perpetual futures agent","decentralized exchange trading","Questflow agent","x402 trading endpoint","crypto perpetuals","leveraged trading agent"],"warnings":["No OpenAPI specification or API documentation available","Output schema is a single unstructured string — responses are unpredictable","Example response is inferred, not sourced from actual API output","Agent may perform real on-chain trades — use with caution and understand financial risk","Regulated activity (derivatives trading) — verify legal compliance in your jurisdiction","Max timeout of 1200 seconds suggests potentially long-running operations"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:68fb94c078e4559a6fb2b674","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x360C17beE775eD2A7573fEBa68caFDE833B95b2B","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:68fb94c078e4559a6fb2b674","description":"Trade perpetuals on Aster, the top DEX with low fees, deep liquidity, multichain support, high leverage and yield.
