You send a text message (POST with an `input` field) and receive a text response from the agent. Payment is handled via the x402 protocol using USDC on the Base Sepolia testnet, with a maximum cost of 0.5 USDC per request (6-decimal token, so 500000 units).\n\nThe endpoint is part of Questflow's broader \"AI Clone\" platform, which aggregates onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) and offers autonomous trading, signal generation, and chat-based interactions. However, the specific capabilities of this particular swarm agent (identified by `qrn:swarm:68f87c2d7aa0f71b3c5e4e5c`) are not documented beyond the generic \"Personal use\" label. There is no OpenAPI spec, no dedicated docs page, and no detailed description of what domain expertise or tools this agent has access to.\n\nThe endpoint accepts POST requests with a JSON body containing an `input` string and returns a JSON object with a `response` string. The maximum timeout is 1200 seconds (20 minutes), suggesting the agent may perform non-trivial processing or multi-step workflows. Payment is sent to `0x6962E41eCFB9F73443Ec27F9e2203A76bfa723c6` in USDC (`0x036CbD53842c5426634e7929541eC2318f3dCF7e`) on Base Sepolia.","tags":[],"capabilities":["x402-payment","text-chat","ai-agent","base-sepolia","usdc-payment","swarm-agent"],"categories":["llm","crypto"],"synonyms":["questflow agent","ai clone chat","x402 agent","paid ai chat","questflow swarm","onchain ai agent","crypto ai assistant"],"warnings":["Base Sepolia is a testnet — this endpoint is not suitable for production use with real funds","No documentation available; /docs, /api, /pricing, and /README all return 404","Agent capabilities are completely undocumented beyond 'Personal use' label","The example response is fabricated since no actual response was captured","Maximum timeout of 1200 seconds suggests potentially very long response times"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f87c2d7aa0f71b3c5e4e5c","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x6962E41eCFB9F73443Ec27F9e2203A76bfa723c6","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f87c2d7aa0f71b3c5e4e5c","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":"0.250","qualityRationale":"No OpenAPI spec, no docs endpoint, no detailed description of agent capabilities.
