The endpoint follows the x402 payment protocol (version 1): callers must include an X-PAYMENT header to satisfy the payment challenge before the agent processes the request.\n\nThe underlying platform, Questflow, markets itself as an \"AI Clone\" system that aggregates prediction markets and on-chain trading venues (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover alpha and execute trades autonomously. However, the specific capabilities of this particular swarm agent are unclear — the listing is titled \"Personal use\" with no further documentation, no OpenAPI spec, and no /docs endpoint. The input schema accepts a single string field (\"input\") and returns a single string field (\"response\").\n\nPayment is required in USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e) on the Base Sepolia testnet, with a maximum amount of 500000 (likely 0.50 USDC given 6 decimals) per request and a timeout of up to 1200 seconds. Because this runs on a testnet, it is likely a development or demo endpoint rather than a production service.","tags":[],"capabilities":["x402-payment-gated","text-in-text-out","base-sepolia-usdc","ai-agent-swarm","questflow-platform"],"categories":["llm","crypto"],"synonyms":["questflow agent","x402 agent","pay-per-message AI","crypto AI clone","swarm agent","micropayment chatbot","on-chain gated LLM"],"warnings":["Endpoint is on Base Sepolia testnet — not suitable for production use","No API documentation or OpenAPI spec available","Agent capabilities and behavior are entirely undocumented","The listing title 'Personal use' provides no meaningful description","Response example is inferred/fabricated since no live response was captured","maxAmountRequired of 500000 likely means 0.50 USDC (6 decimals) but this is inferred"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f882227aa0f71b3c5e86dd","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x6E947f1E09918Af7141903De63Be8D02D211d5e6","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f882227aa0f71b3c5e86dd","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":"No OpenAPI spec, no documentation endpoint, no usage examples, and the listing title/description are generic ('Personal use').
