It accepts a text prompt (POST with an \"input\" string field) and returns a text response containing financial data or analysis. Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC, with a maximum charge of 0.1 USDC per request (100000 units in 6-decimal USDC).\n\nThe endpoint is part of Questflow's broader AI agent platform, which aggregates data from multiple onchain and offchain markets. However, the specific capabilities of this \"Financial Datasets\" agent — such as which datasets it covers, what financial instruments or markets it supports, and the depth of its responses — are not documented beyond the generic agent schema. The output schema indicates a simple request/response pattern: you send a string message and receive a string response.\n\nBecause there is no OpenAPI spec, no dedicated documentation page, and no example responses available, the exact scope and quality of the financial data returned is unknown. The endpoint is currently on a development/testnet infrastructure (api-dev, base-sepolia), suggesting it may not be production-ready. Callers should treat this as an experimental endpoint.","tags":[],"capabilities":["financial-data-query","x402-payment","base-sepolia-usdc","text-in-text-out","agent-endpoint"],"categories":["finance","llm"],"synonyms":["financial data API","financial datasets agent","Questflow financial agent","x402 financial data","onchain financial data","crypto market data","financial analysis agent"],"warnings":["No OpenAPI or dedicated documentation available — agent capabilities are unknown beyond the generic schema.","Endpoint is on development infrastructure (api-dev) and Base Sepolia testnet — not production-ready.","Example response is fabricated/inferred; actual response format and content are unverified.","The description 'Financial Datasets' is extremely generic with no specifics on coverage, freshness, or data sources."],"endpointUrl":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:6891bd58092f17ff446a3b4c","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x036CbD53842c5426634e7929541eC2318f3dCF7e","extra":{"name":"USDC","version":"2"},"payTo":"0x3Ed23414A3Af941B06332710AE2357c2a093dcb7","scheme":"exact","network":"base-sepolia","mimeType":"application/json","resource":"https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:6891bd58092f17ff446a3b4c","description":"Financial Datasets | 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":"100000","maxTimeoutSeconds":1200}]},"qualityScore":"0.250","qualityRationale":"The endpoint has a valid x402 challenge with a minimal output schema, but there is no OpenAPI spec, no documentation, no example responses, and no details on which financial datasets are actually available.
