{"id":"5c14c855-6cf4-4d2d-b77c-df9d943a66fe","shortId":"FKRRXT","kind":"x402","title":"Pay-per-query deep Web3 research agent via x402 on Base","tagline":"Pay-per-query deep Web3 research agent via x402 on Base","description":"Deep WEB3 Research is an x402-enabled AI agent endpoint hosted by Questflow that performs deep research across Web3 topics. It accepts a natural-language prompt and returns a text response generated by a multi-agent swarm. Payment is handled via the x402 protocol on the Base network using USDC (asset 0x8335…2913), with a maximum cost of 0.50 USDC per request and a timeout of up to 1200 seconds (20 minutes).\n\nThe endpoint accepts a POST request with a JSON body containing a single required field, `input` (string), which is your message or research query to the agent. The response includes a `response` field (string) with the agent's answer. The x402 challenge is live and well-formed, confirming the endpoint is operational.\n\nQuestflow is a platform focused on autonomous AI agents (\"Clones\") that scan and trade across onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. This particular swarm endpoint is designed for Web3 research rather than trading. Documentation beyond the x402 challenge itself is sparse — no OpenAPI spec, no dedicated docs page, and no detailed description of what \"deep WEB3 research\" covers or which data sources the swarm consults. Users should expect a general-purpose Web3 research assistant but should verify output quality empirically.","tags":[],"capabilities":["web3-research","x402-payment","base-network","usdc-payment","natural-language-query","multi-agent-swarm","json-api"],"categories":["llm","crypto","research"],"synonyms":["web3 research agent","crypto research API","blockchain research endpoint","questflow swarm","onchain research","DeFi research agent","x402 crypto agent","web3 question answering"],"warnings":["No OpenAPI or dedicated API documentation available","No detailed description of data sources or research methodology behind the swarm","Example response is inferred/illustrative — actual output format and depth are unknown","Maximum timeout of 1200 seconds suggests potentially long response times"],"endpointUrl":"https://api.questflow.ai/x402/swarm/qrn:swarm:689c56949b0e5b463f62ce01","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0xa07AF235A87A51eD280c094B7C70ac748cF3F6f2","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/swarm/qrn:swarm:689c56949b0e5b463f62ce01","description":"Deep WEB3 research | 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 x402 challenge is live and includes a clear outputSchema with input/output definitions, confirming the endpoint works.
