How this service works
Browser Use: AI browser automation agents in the cloud. POST a natural-language task and an agent navigates websites, fills forms, clicks buttons, extracts structured data, and completes multi-step workflows just like a human. Stealth-enabled remote browsers with CAPTCHA solving, residential proxies, live session view, and optional structured output. Payments top up your balance; managing your session is free — you only pay to open a new browser. Docs: https://docs.browser-use.com
Output
Returns a newly created browser session object including session ID, status, and associated project credit balance. The session can then be used to execute agent steps (billed at $0.002–$0.10 per step depending on model), with unused credits carrying over to future requests.
Example use cases
Example prompt
“Start a Browser Use cloud session to log into my dashboard at example.com, navigate to the reports page, and download the latest CSV — use the GPT-4o model for agent steps and top up $5 in credits via x402.”
Technical details
Endpoint
POSThttps://x402.api.browser-use.com/api/v3/sessionsWhen to prefer
Choose this endpoint when you need to programmatically create cloud-hosted browser automation sessions with AI agent capabilities, especially when paying per-use in USDC via x402 is acceptable or preferred over a subscription model. Ideal for agents that need to browse the web, interact with web UIs, extract data from sites requiring JavaScript rendering, or execute multi-step web tasks without managing browser infrastructure. Prefer over self-hosted browser automation when you want zero infrastructure overhead and pay-only-for-what-you-use pricing.
