Callers send a text message via POST and receive a text response from the agent. Payment is handled through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.5 USDC per request.\n\nQuestflow is a platform for creating autonomous AI \"Clones\" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover trading alpha, execute trades, and generate revenue. This particular endpoint is labeled \"Personal use\" and appears to be a single agent within Questflow's swarm system, identified by the QRN `qrn:swarm:68f9da71aa9a530561e6dfea`. The endpoint's output schema indicates a simple request/response pattern: you POST a JSON body with an `input` string field and receive a JSON object containing a `response` string field.\n\nNote that this endpoint operates on the Base Sepolia testnet, meaning it uses testnet USDC — not real funds. Documentation beyond the x402 challenge and the Questflow landing page is essentially absent; there is no OpenAPI spec, no dedicated API docs, and no detailed description of what this specific agent does beyond \"Personal use.\" The agent's actual capabilities, knowledge domain, and behavior are unknown.","tags":[],"capabilities":["x402-payment","conversational-agent","base-sepolia-testnet","usdc-payment","questflow-swarm","post-endpoint"],"categories":["llm","crypto"],"synonyms":["Questflow agent","AI clone","swarm agent","x402 chatbot","pay-per-message agent","onchain AI agent","Questflow swarm endpoint"],"warnings":["Operates on Base Sepolia testnet — not real USDC, not suitable for production","No API documentation or OpenAPI spec available","Agent purpose and capabilities are undocumented beyond the label 'Personal use'","The example response is fabricated to match the output schema; actual agent behavior is unknown","No rate limits, SLAs, or usage terms documented"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9da71aa9a530561e6dfea","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x0B7465f9817a2b77E44A1E248Aa5b3E9C2Ccdedf","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9da71aa9a530561e6dfea","description":"Personal use | 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":"500000","maxTimeoutSeconds":1200}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge confirmed) and has a basic output schema, but there is no OpenAPI spec, no dedicated documentation, no examples, and the agent's actual purpose beyond 'Personal use' is unknown.
