It accepts a natural-language message (via a POST body with an \"input\" field) and returns a text response covering real-time ETH price, market data, supply metrics, historical charts, and exchange activity. The agent is hosted on Questflow's swarm infrastructure at a development API endpoint.\n\nPayment is handled via the x402 protocol on the Base Sepolia testnet. The accepted asset is USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a maximum amount of 500,000 units (denominated in the token's smallest unit). The payment timeout is 1,200 seconds. Because this uses Base Sepolia (a testnet), the endpoint appears to be in a development or staging phase rather than production.\n\nNo dedicated API documentation, OpenAPI spec, or usage examples were found beyond the x402 challenge's outputSchema. The outputSchema indicates a simple request/response pattern: send a string prompt, receive a string response. The endpoint is live and returns a proper 402 challenge when called without payment.","tags":[],"capabilities":["ethereum-dashboard","real-time-price","market-data","supply-metrics","historical-charts","exchange-activity","x402-payment","base-sepolia-testnet","natural-language-input","agent-response"],"categories":["crypto","data","llm"],"synonyms":["ETH dashboard","Ethereum price API","ETH market data","crypto dashboard agent","Ethereum analytics","ETH supply data","Ethereum exchange activity"],"warnings":["Endpoint uses Base Sepolia testnet — not suitable for production payments","No API documentation or OpenAPI spec found","Response example is inferred; actual output format is unverified","Development/staging endpoint (api-dev subdomain) — availability may be unstable"],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f8b70388e91d0ba6c9bdcd","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x16BA8045407D644b8ebDb1feE69754aD39896EC0","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/swarm/qrn:swarm:68f8b70388e91d0ba6c9bdcd","description":"A comprehensive Ethereum dashboard displaying real-time price, market data, supply, historical charts, and exchange activity with responsive design and visualizations. | 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":"0.450","qualityRationale":"The endpoint is live and returns a valid x402 challenge with an outputSchema, but there is no dedicated documentation, no OpenAPI spec, no usage examples, and the endpoint runs on a testnet (Base Sepolia), suggesting it is still in development.
