It exposes a single AI agent (identified by `qrn:swarm:68f6f19ab496db62cf748761`) that accepts a text input via HTTP POST and returns a text response, gated behind an x402 micropayment in USDC on the Base Sepolia testnet. The maximum payment required is 0.5 USDC (500000 in token units), and the endpoint allows up to 1200 seconds for processing.\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 appears to be a development/testnet instance of one such agent, labeled \"new creation.\" The agent's specific capabilities, persona, or domain expertise are not documented beyond the generic description.\n\nBecause this is a dev-environment endpoint on a testnet, there is no production SLA, no OpenAPI schema, and no detailed documentation available. The `/docs`, `/api`, `/pricing`, and `/README` paths all return 404. The only structured metadata comes from the x402 challenge response, which defines the input/output schema (a single string in, a single string out) and payment terms. Users should treat this as an experimental or staging endpoint.","tags":[],"capabilities":["x402-payment","ai-agent-chat","base-sepolia-usdc","http-post","text-in-text-out"],"categories":["llm","crypto"],"synonyms":["questflow agent","x402 ai agent","paid ai chat","onchain agent","micropayment llm","questflow swarm","crypto ai clone"],"warnings":["Development/testnet endpoint (Base Sepolia) — not suitable for production use","No documentation available; /docs, /api, /pricing, /README all return 404","Agent purpose and capabilities are undocumented beyond 'new creation'","No OpenAPI schema provided","Response schema is inferred from x402 outputSchema — actual responses may differ"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f6f19ab496db62cf748761","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x2f21C05311A0Cd55E1c36fF928EcFb87a0c93c8c","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f6f19ab496db62cf748761","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 documentation pages (all 404), no examples, and the endpoint is on a dev/testnet environment.
