It is accessed over HTTP POST with an x402 payment header, settling in USDC on the Base network. The maximum cost per call is 0.50 USDC (500000 in 6-decimal units), and the endpoint allows up to 1200 seconds (20 minutes) for a response, suggesting it can handle long-running browser tasks.\n\nThe input schema is minimal: a single required string field called \"input\" containing your message to the agent. The output is likewise a single string field called \"response\". No OpenAPI spec, dedicated documentation page, or usage examples are published by the provider — the only technical contract available is the x402 challenge metadata returned by the endpoint itself.\n\nQuestflow is primarily an AI-agent platform focused on onchain market aggregation and autonomous trading clones. This particular endpoint appears to be one of their swarm agents exposed for external consumption via the x402 micropayment protocol. Because there is no public documentation beyond the x402 challenge and the provider's marketing site, the exact browser-automation capabilities (e.g., supported sites, JavaScript execution, screenshot capture, cookie handling) remain unspecified.","tags":[],"capabilities":["browser-automation","x402-payment","usdc-base","natural-language-input","managed-agent","long-running-tasks","web-interaction"],"categories":["automation","web"],"synonyms":["web automation","headless browser","browser agent","web scraping agent","Questflow browser","x402 browser","managed browser","web interaction API","AI browser agent"],"warnings":["No public documentation or OpenAPI schema available — all technical details inferred from x402 challenge metadata only.","Exact browser automation capabilities (screenshot support, JS execution, cookie handling, site restrictions) are undocumented.","Example response is fabricated for illustration; actual output format is unverified.","Provider's main product is an AI trading clone platform; this endpoint's maintenance priority is unclear.","Maximum cost of 0.50 USDC per call with a 20-minute timeout suggests potentially expensive, long-running operations."],"endpointUrl":"https://api.questflow.ai/x402/swarm/qrn:swarm:68f096b20ebd74a7911b08b6","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0xf33CAC2bB6B26e7615B1873c84e4174Ae193A9aa","extra":{"name":"AUSD","version":"2"},"payTo":"0x627d74adfd10EC754BAE10e2514a2461C83aD8F0","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.questflow.ai/x402/swarm/qrn:swarm:68f096b20ebd74a7911b08b6","description":"Provide browser automation functionality for any model, supporting secure, scalable, and fully managed web interactions. | 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":"0.300","qualityRationale":"No OpenAPI spec, no dedicated docs, no usage examples, and no detailed capability description exist.
