The endpoint accepts a POST request with a JSON body containing an \"input\" string field (your message to the agent) and returns a JSON response with a \"response\" string field. Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e), with a maximum amount of 500,000 units (likely 0.50 USDC given 6 decimals) per request and a timeout of up to 1,200 seconds.\n\nQuestflow is a platform for creating autonomous AI \"Clones\" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) for trading, signal generation, and revenue earning. This particular endpoint is labeled \"new creation\" and appears to be a newly provisioned swarm agent. No further documentation, OpenAPI spec, or detailed capability description is available beyond the x402 challenge metadata and the outputSchema embedded in it.\n\nBecause this is a development API on a testnet with minimal documentation and a generic title/description, the exact capabilities of the underlying agent are unclear. The endpoint is confirmed live (returns 402 on unauthenticated POST), but users should treat this as an experimental or early-stage offering.","tags":[],"capabilities":["x402-payment","text-in-text-out","swarm-agent","base-sepolia-usdc","pay-per-request","autonomous-agent"],"categories":["llm","crypto","agents"],"synonyms":["questflow agent","questflow swarm","x402 agent","pay-per-call AI","onchain AI agent","crypto trading agent","questflow clone","paid chat agent"],"warnings":["Development API (api-dev) on Base Sepolia testnet — not a production endpoint","Generic title and description ('new creation') with no meaningful documentation","No OpenAPI spec or detailed docs available at any crawled path","Underlying agent capabilities are entirely unknown; response quality cannot be assessed","USDC asset is on Sepolia testnet, not mainnet"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f1f4219c162996ee72b3cd","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x0AfAF05Ee34A2c90f88D6f293cD1B8e23750E886","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f1f4219c162996ee72b3cd","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":"0.350","qualityRationale":"The endpoint is confirmed live (402 challenge captured) with a clear outputSchema for input/output, but the title and description are generic (\"new creation\"), there is no OpenAPI spec, no dedicated documentation, and this is a development/testnet deployment.
