The agent is described in its payment challenge as \"The AI-powered developer platform to build, scale, and deliver secure software.\" It accepts a POST request with a JSON body containing an `input` string (your message to the agent) and returns a `response` string. Payment is handled via the x402 protocol on the Base network using USDC (asset `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`), with a maximum cost of 100,000 base units per call (0.10 USDC assuming 6-decimal USDC) and a timeout of up to 1,200 seconds.\n\nQuestflow is a platform for building and deploying AI agents (\"Clones\") that operate autonomously across onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The broader platform focuses on crypto-native AI agents with their own wallets and tokens. However, this specific endpoint's description suggests it is oriented toward software development assistance rather than market trading. Because no dedicated API documentation, OpenAPI spec, or detailed agent capability description was found, the exact scope of what this agent can do beyond accepting a text prompt and returning a text response is unclear.\n\nThe endpoint is live and returns a valid x402 challenge on POST. The output schema is simple: one required input field (`input`: string) and one output field (`response`: string). No authentication beyond the x402 payment header is required.","tags":[],"capabilities":["x402-payment","ai-agent","text-generation","base-network","usdc-payment","post-endpoint","questflow-agent"],"categories":["llm","crypto"],"synonyms":["questflow agent","ai developer assistant","x402 ai agent","pay-per-call llm","questflow x402","software development ai","base network agent"],"warnings":["No API documentation or OpenAPI spec found; /docs, /api, /pricing, /README all return 404","The agent description ('AI-powered developer platform to build, scale, and deliver secure software') appears generic and may not accurately reflect the agent's actual capabilities","The Questflow landing page focuses on crypto market trading clones, which contradicts the developer-platform description — the agent's true purpose is unclear","Response content and quality cannot be verified without making a paid call"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:68cd37a11e25c97d05356aad","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x3ba3589B6b0E1fE82Bcb1cdfC4e3754C26dbBa29","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:68cd37a11e25c97d05356aad","description":"The AI-powered developer platform to build, scale, and deliver secure software. | 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 x402 challenge and a clear output schema, but there is no API documentation, no OpenAPI spec, and the agent's actual capabilities are undocumented.
