It accepts a text message via POST and returns a response from a Web3 trading-focused agent. The endpoint is gated by an x402 payment challenge requiring USDC on Base Sepolia, with a maximum cost of 0.50 USDC per request (6-decimal token, maxAmountRequired 500000). The agent is part of Questflow's \"AI Clone\" swarm infrastructure, which aggregates onchain markets including Polymarket, Pump.fun, Opinion Labs, and OKX.\n\nThe input/output schema is minimal: send a JSON body with an \"input\" string field containing your message, and receive a JSON response with a \"response\" string field. The endpoint supports a maximum timeout of 1200 seconds (20 minutes), suggesting the agent may perform non-trivial reasoning or external lookups before responding. Payment is sent to address 0xa5F42B1a18d406A17D605b1c4207210Fa37Fe169 using the USDC contract at 0x036CbD53842c5426634e7929541eC2318f3dCF7e on Base Sepolia.\n\nDocumentation is sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed description of what queries the agent can handle or what data sources it accesses at inference time. The Questflow landing page describes autonomous trading clones that scan markets, detect patterns, and execute trades, but it is unclear how much of that functionality is exposed through this single chat-style endpoint versus the broader Questflow platform.","tags":[],"capabilities":["x402-payment","web3-trading","prediction-markets","onchain-market-aggregation","chat-agent","base-sepolia-usdc"],"categories":["crypto","llm","trading"],"synonyms":["Web3 trading bot","crypto trading agent","Polymarket agent","onchain trading AI","Questflow swarm","prediction market bot","DeFi chat agent"],"warnings":["Uses Base Sepolia testnet — not production mainnet USDC","No API documentation or OpenAPI spec available","Agent capabilities are inferred from marketing copy; actual behavior is unverified","20-minute max timeout suggests potentially long response times","Endpoint path contains a dynamic swarm ID that may change"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68fa09a8c87f09b65914cbac","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0xa5F42B1a18d406A17D605b1c4207210Fa37Fe169","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68fa09a8c87f09b65914cbac","description":"Web3 Trader | 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":"0.450","qualityRationale":"The endpoint is live and returns a valid 402 challenge with a clear outputSchema.
