It exposes a single AI agent behind a paywall using the x402 payment protocol on the Base Sepolia testnet. The agent accepts a text message via a POST request and returns a text response. Payment is made in USDC (test token on Base Sepolia) with a maximum cost of 0.5 USDC per request (500000 in token units) and a timeout of up to 1200 seconds.\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 \"new creation\" and appears to be a newly created agent swarm instance. No further documentation, OpenAPI spec, or detailed capability description is available for this specific agent beyond the x402 challenge metadata.\n\nBecause this endpoint runs on a development subdomain and uses the Base Sepolia testnet, it is likely intended for testing and experimentation rather than production use. There is no published documentation for the API beyond what the x402 challenge provides, and the agent's specific behavior or domain expertise is unknown.","tags":[],"capabilities":["x402-payment","ai-agent-chat","base-sepolia-testnet","usdc-micropayment","post-json-api","questflow-swarm"],"categories":["llm","crypto","agent"],"synonyms":["questflow agent","x402 ai agent","pay-per-call agent","crypto ai clone","onchain agent","micropayment chatbot","questflow swarm"],"warnings":["Development/testnet endpoint (api-dev, Base Sepolia) — not suitable for production use","No API documentation available; /docs, /api, /pricing, /README all return 404","Agent labeled 'new creation' with no description of its specific capabilities or domain","Response schema is inferred from x402 outputSchema — actual responses may differ","USDC asset address is a testnet token, not real USDC"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f1f2009c162996ee72af5e","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x74d4783C087fEdf7EE7d2e27cD3C9e152F967Dea","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f1f2009c162996ee72af5e","description":"new creation | 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 examples, and the agent is on a dev/testnet domain with a generic title ('new creation').
