Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e), with a maximum charge of 0.5 USDC per request (500000 in token units). The endpoint accepts HTTP POST requests with a JSON body containing an `input` string field and returns a JSON object with a `response` string field.\n\nQuestflow is a platform focused on autonomous AI agents (\"Clones\") that operate across onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The broader platform lets users create AI agents that scan markets, execute trades, and generate revenue. However, this specific endpoint is labeled \"Personal use\" and its exact agent behavior or specialization is not documented beyond the generic input/output schema.\n\nNotably, this endpoint is on a development/staging domain (api-dev.intra-tls2.dctx.link) and uses the Base Sepolia testnet, which strongly suggests it is not a production service. There is no OpenAPI spec, no dedicated documentation, and no detailed description of what the agent actually does beyond accepting a message and returning a response. The maximum timeout of 1200 seconds (20 minutes) indicates the agent may perform complex or long-running tasks before responding.","tags":[],"capabilities":["x402-payment","ai-agent-chat","base-sepolia-usdc","http-post","json-io","autonomous-agent","swarm-endpoint"],"categories":["llm","crypto","agents"],"synonyms":["questflow agent","ai clone","x402 agent","pay-per-message ai","onchain ai agent","swarm agent","questflow swarm","micropayment chatbot"],"warnings":["Endpoint is on a development/staging domain (api-dev), not production","Uses Base Sepolia testnet — not real USDC; likely for testing only","No OpenAPI spec or documentation available","Agent behavior and capabilities are completely undocumented","The 'Personal use' label provides no meaningful description of functionality","Maximum timeout of 1200 seconds suggests potentially very slow responses"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f21a481964b63f34ad8bd9","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0xD994D8B57c3516A5E0FcC3730e1A75A6D2655e9B","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f21a481964b63f34ad8bd9","description":"Personal use | 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":"The endpoint has a valid x402 challenge with input/output schema, but there is no OpenAPI spec, no documentation, no examples, and it runs on a testnet dev domain.
