It accepts a natural-language text prompt via a simple POST request with an `input` field and returns an agent-generated analysis as a string response.\n\nThe endpoint is live and uses the x402 payment protocol on the Base network, accepting USDC (asset 0x8335…2913) with a maximum charge of 500,000 units (0.50 USDC at 6 decimals) per request. The maximum timeout is 1,200 seconds (20 minutes), reflecting the multi-step agentic workflow that may involve searching, retrieving, and synthesizing information from multiple sources before returning a consolidated answer.\n\nDocumentation beyond the x402 challenge and the Questflow landing page is not available. There is no OpenAPI spec, no dedicated docs page, and no usage examples from the provider. The input/output schema is minimal: send `{\"input\": \"<your question>\"}` and receive `{\"response\": \"<agent answer>\"}`. The Questflow platform focuses on AI agent clones for onchain market trading and alpha discovery, and this endpoint appears to be one of many swarm agents exposed through their x402 gateway.","tags":[],"capabilities":["stock-market-analysis","real-time-market-data","financial-news-search","exa-search-integration","perplexity-ai-integration","natural-language-query","x402-payment","usdc-base-network","agentic-workflow"],"categories":["finance","search","llm"],"synonyms":["stock analysis API","market data agent","financial research tool","stock market AI","equity analysis endpoint","market intelligence agent","Questflow stock agent","Perplexity finance search"],"warnings":["No OpenAPI spec or dedicated API documentation available from the provider","Output is free-text from an AI agent — format, accuracy, and completeness are not guaranteed","Max timeout of 1200 seconds suggests potentially long response times","Exact USDC cost per request (maxAmountRequired 500000 = 0.50 USDC assuming 6 decimals) is inferred from the challenge but not confirmed by docs","Financial analysis output should not be treated as investment advice"],"endpointUrl":"https://api.questflow.ai/x402/swarm/qrn:swarm:68c4d1991dad762112b40f03","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x80AE6c382241D3b96F6408a7cc8266AE5aC8De33","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/swarm/qrn:swarm:68c4d1991dad762112b40f03","description":"A comprehensive stock market analysis tool that leverages Exa search and Perplexity AI to provide LLMs and agentic workflows with seamless access to real-time market data, historical stock performance, financial news, and market insights.
