It accepts a text prompt via HTTP POST and returns a text response from the agent. Payment is handled through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum cost of 0.5 USDC per request and a timeout of up to 1200 seconds (20 minutes).\n\nThe endpoint is part of Questflow's \"swarm\" system, which appears to be a collection of AI agents that can be invoked programmatically. Questflow's broader platform focuses on autonomous AI clones for onchain market scanning, trading, and research across platforms like Polymarket, Pump.fun, OKX, and Opinion Labs. The specific capabilities of this \"Researcher\" agent are not documented beyond its name and the generic input/output schema — it accepts a string message and returns a string response.\n\nNo OpenAPI spec, detailed documentation, or usage examples are available from the provider. The endpoint is currently on a development/testnet domain (api-dev, base-sepolia), suggesting it may not yet be production-ready. Prospective users should treat this as an experimental endpoint.","tags":[],"capabilities":["ai-agent","research-agent","x402-payment","usdc-payment","base-sepolia","text-in-text-out","http-post"],"categories":["llm","crypto"],"synonyms":["Questflow researcher","AI research agent","x402 agent","paid AI agent","crypto research bot","Questflow swarm agent","micropayment AI"],"warnings":["Endpoint is on a development domain (api-dev) and uses Base Sepolia testnet — not production-ready","No API documentation, OpenAPI spec, or detailed capability description available","The 'Researcher' agent's specific capabilities and knowledge scope are undocumented","Response example is inferred/fabricated from the schema; actual output format may differ","Maximum timeout of 1200 seconds suggests potentially long-running requests"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68edbf9a9a89cedc55909218","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x0ebC3107Ecb36eD7BB1a1C8E1087b81E4FDE044e","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68edbf9a9a89cedc55909218","description":"Researcher | 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":"0.300","qualityRationale":"No OpenAPI spec, no documentation pages, no usage examples, and the endpoint is on a dev/testnet domain.
