The endpoint follows the x402 payment protocol: callers must include an X-PAYMENT header with a valid payment proof. Each request costs up to 0.50 USDC (500000 units in 6-decimal USDC), and the payment is sent to a specified wallet address.\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 is labeled \"Personal use\" and appears to be a single agent instance within Questflow's swarm infrastructure. The input schema is minimal: a POST request with a JSON body containing an \"input\" string field (your message to the agent), and the output is a JSON object with a \"response\" string field.\n\nDocumentation is sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed description of what this specific agent does beyond the generic \"Personal use\" label. The endpoint is on a development/staging domain (api-dev), suggesting it may not be production-stable. The x402 challenge metadata and the Questflow landing page are the only sources of information available.","tags":[],"capabilities":["x402-payment","text-chat","ai-agent","usdc-micropayment","base-sepolia-testnet","questflow-swarm"],"categories":["llm","crypto"],"synonyms":["questflow agent","ai clone","swarm agent","x402 chat","paid ai endpoint","questflow swarm","micropayment ai","onchain ai agent"],"warnings":["Endpoint is on a development domain (api-dev) — may be unstable or ephemeral","No OpenAPI spec or documentation available","Agent behavior and capabilities are undocumented; 'Personal use' label is vague","Payment uses Base Sepolia testnet — not real USDC","Response example is fabricated for illustration; actual agent output is unknown"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9cbd8171bbfe8621867a8","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x5702f2EA10236c30d312677aA35F7bE9AD92f5dB","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9cbd8171bbfe8621867a8","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 pages, no usage examples, and the endpoint is on a dev/staging domain.
