The agent accepts a text prompt (the `input` field) and returns a text response. Payment is handled via the x402 protocol on the Base network using USDC (asset 0x8335…2913), with a maximum charge of 0.1 USDC per request (100000 in 6-decimal units) and a generous 1200-second timeout, suggesting the agent may perform multi-step browser interactions before returning a result.\n\nThe endpoint is a POST request to `https://api.questflow.ai/x402/agent/qrn:agent:68cbd3ea1eac16d8cffc6041`. Callers must include an `X-PAYMENT` header conforming to x402 v1. The request body is JSON with a single required string field `input` containing the user's instruction to the agent. The response body contains a `response` string field with the agent's output.\n\nQuestflow is primarily an AI-agent platform focused on onchain market aggregation and autonomous trading clones. This particular agent appears to be a browser-automation service exposed through their x402 infrastructure. Documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and no detailed usage guide. The output schema and payment terms are derived entirely from the x402 challenge header. Actual browser-automation capabilities, supported sites, rate limits, and reliability characteristics are unknown.","tags":[],"capabilities":["web-automation","browser-use","x402-payment","base-network","usdc-payment","mcp-server","agent-invocation","text-in-text-out"],"categories":["automation","agent"],"synonyms":["browser automation","web scraping agent","browser-use MCP","headless browser API","web agent","Questflow agent","server-side browser","x402 web automation"],"warnings":["No API documentation or OpenAPI spec available — /docs, /api, /pricing, /README all return 404","Agent capabilities are inferred solely from the title 'browser-use cloud MCP server'; no detailed feature list exists","Payment amount (up to 0.1 USDC) and 1200s timeout are from the x402 challenge but actual billing behavior is unverified","Questflow's main site focuses on trading clones, not browser automation — this agent's maturity and support level are unclear"],"endpointUrl":"https://api.questflow.ai/x402/agent/qrn:agent:68cbd3ea1eac16d8cffc6041","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x5d82457cEDCc94e57a2988300A7d4421444fc09C","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/agent/qrn:agent:68cbd3ea1eac16d8cffc6041","description":"Introducing browser-use cloud MCP server - web automation for any model through server-side MCP. | 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":"0.300","qualityRationale":"The listing is based almost entirely on the x402 challenge header; there is no OpenAPI spec, no documentation page, no usage examples, and no detailed capability description.
