The agent accepts a natural-language message as input and returns a text response with the requested crypto market information. It supports both automatic and manual refresh capabilities for up-to-date pricing.\n\nPayment is handled via the x402 protocol on the Base Sepolia testnet using USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e). The maximum amount required per request is 500,000 units (likely 0.50 USDC given 6-decimal USDC), with a maximum timeout of 1,200 seconds. The endpoint accepts HTTP POST requests with a JSON body containing an \"input\" string field and returns a JSON object with a \"response\" string field.\n\nThe agent is part of the Questflow platform, which aggregates onchain markets and provides AI-driven trading and market intelligence tools. Documentation is sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed API reference beyond the x402 challenge metadata. The endpoint appears to be on a development/staging domain (api-dev), suggesting it may not yet be production-ready.","tags":[],"capabilities":["crypto-price-dashboard","real-time-market-data","bitcoin-price","ethereum-price","trend-charts","x402-payment","base-sepolia-usdc","natural-language-query","ai-agent"],"categories":["crypto","market-data"],"synonyms":["crypto dashboard","bitcoin price API","ethereum price API","BTC ETH market data","crypto trend charts","real-time crypto prices","Questflow swarm agent","x402 crypto endpoint"],"warnings":["Endpoint is on a development domain (api-dev.intra-tls2.dctx.link) — may be unstable or ephemeral","Payment network is Base Sepolia (testnet), not mainnet — real monetary value unclear","No OpenAPI spec or dedicated documentation available","No docs, pricing, or README pages found on the server (all return 404)","Response example is inferred, not sourced from actual API output"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68ef7e429c48f862fcc4d377","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0xdB122D27d5e6009A05C9Def954672d1e02CC93Cb","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68ef7e429c48f862fcc4d377","description":"Real-time dashboards displaying Bitcoin and Ethereum prices, market data, and trend charts, with automatic and manual refresh capabilities. | 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 beyond the x402 challenge metadata.
