It is accessible as an x402 endpoint, meaning callers pay per request using USDC on the Base network. The endpoint accepts a POST request with a simple JSON body containing an `input` string (your search query) and returns a `response` string with the agent's answer.\n\nPayment is handled via the x402 protocol: the endpoint returns a 402 challenge requiring an `X-PAYMENT` header with a payment proof. The maximum amount required per call is 100,000 units of USDC (0.10 USDC given 6 decimals), and the maximum timeout for a response is 1,200 seconds (20 minutes), reflecting the potentially long-running nature of deep search tasks.\n\nQuestflow is a platform focused on autonomous AI agents for onchain markets and information retrieval. This particular agent is identified by the QRN `qrn:agent:687df69ab234010b7d3317e5`. No OpenAPI spec or detailed API documentation was found beyond the x402 challenge schema itself, so usage details are inferred from the challenge payload.","tags":[],"capabilities":["deep-web-search","google-gemini","x402-payment","usdc-base","autonomous-agent","natural-language-query"],"categories":["search","llm"],"synonyms":["web search API","Gemini search agent","deep search","internet research agent","AI web search","Questflow agent","paid search endpoint"],"warnings":["No OpenAPI or dedicated API documentation found","Response format is inferred from the x402 outputSchema, not from actual response samples","Max timeout of 1200 seconds suggests potentially very long response times","No rate limits or usage quotas documented"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:687df69ab234010b7d3317e5","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x330e5e07676339F034881135515A96C4a3274207","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:687df69ab234010b7d3317e5","description":"Can perform deep search on the web using Google Gemini model. | 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":"0.550","qualityRationale":"The endpoint is live with a valid 402 challenge and includes an outputSchema describing input/output fields.
