It exposes a single POST method that accepts a text message and returns a response from an AI agent within the Questflow \"swarm\" system. Payment is required via the x402 protocol using USDC on Base Sepolia (testnet), with a max amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC).\n\nQuestflow is a platform focused on autonomous AI agents (\"Clones\") that aggregate onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The agents scan markets, execute trades, and generate signals. This particular endpoint is labeled \"new project\" with no further description, so its specific agent behavior is unknown. The outputSchema in the 402 challenge indicates a simple request/response pattern: POST a JSON body with an \"input\" string field and receive a \"response\" string field.\n\nNote that this endpoint is on a development/testnet infrastructure (Base Sepolia, api-dev subdomain). There is no public documentation, no OpenAPI spec, and the project title and description are both generic placeholders (\"new project\"). Treat this as an early-stage or experimental deployment.","tags":[],"capabilities":["x402-payment","ai-agent-chat","post-json","base-sepolia-usdc","swarm-agent"],"categories":["llm","crypto"],"synonyms":["questflow agent","ai clone","swarm agent","x402 chat","paid ai agent","questflow swarm","onchain ai agent"],"warnings":["Endpoint is on development infrastructure (api-dev subdomain) and uses Base Sepolia testnet — not production-ready","Project title and description are both generic placeholders ('new project') with no meaningful detail about agent behavior","No public documentation or OpenAPI spec available","Example response is inferred from the outputSchema, not from an actual API call"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68db8960622da9e5eb2e5596","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x4c6e46ec9d8AA3D61094124B083F112a87ea22E4","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68db8960622da9e5eb2e5596","description":"new project | 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 live (402 challenge captured) and has a basic outputSchema, but the project title and description are both generic placeholders (\"new project\").
