The endpoint accepts a POST request with a text message and returns a string response from the agent. Payment is handled via the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.50 USDC per request (500000 in token units) and a timeout of up to 1200 seconds.\n\nQuestflow is a platform focused on AI \"Clones\" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) for autonomous trading, alpha discovery, and revenue generation. This particular endpoint appears to be a general-purpose conversational agent within Questflow's swarm infrastructure, though the exact capabilities and specialization of the agent behind this endpoint are not documented beyond the generic label \"Personal use.\"\n\nNotably, this is a development/testnet endpoint (Base Sepolia, api-dev subdomain), so it should not be treated as production-grade. There is no OpenAPI spec, no dedicated documentation page, and no detailed description of what the agent actually does beyond accepting a message and returning a response. The output schema is minimal: input is a string message, output is a string response.","tags":[],"capabilities":["x402-payment","conversational-agent","base-sepolia-usdc","swarm-agent","pay-per-request"],"categories":["llm","crypto"],"synonyms":["questflow agent","x402 chatbot","paid AI agent","swarm endpoint","questflow swarm","micropayment agent","onchain AI agent"],"warnings":["Development/testnet endpoint (api-dev subdomain, Base Sepolia network) — not production-ready","No OpenAPI spec or documentation available","Agent capabilities are entirely undocumented; 'Personal use' is the only description","The example response is fabricated to illustrate the schema; actual agent behavior is unknown","maxAmountRequired of 500000 USDC units (0.50 USDC) is on a testnet token, not real funds"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9cb150f57b44388faafa1","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x8a3c0DBAf424c93CbE9De76F64216C1340ef974F","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f9cb150f57b44388faafa1","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 a minimal input/output schema, but there is no OpenAPI spec, no documentation, no examples, and the description is just 'Personal use'.
