How this service works
Create a new browser session ($0.10). Optionally pass sessionId to resume an existing Browserbase session. Returns sessionId (Browserbase session ID) to use for all subsequent calls.
Output
Returns a sessionId (Browserbase session ID) string that must be passed to all subsequent browser automation API calls to identify and interact with the created or resumed browser session.
Example use cases
Automated web scraping agent
“Spin up a new browser session so my agent can log into a website and scrape the latest product pricing data.”
Resume multi-step form filling
“Resume my existing Browserbase session with ID 'abc123' so I can continue filling out that multi-page application form where I left off.”
AI agent web navigation workflow
“Create a fresh browser session for my AI agent to navigate to a checkout page, add items to the cart, and capture a screenshot of the order summary.”
Technical details
Endpoint
POSThttps://stable-browser-git-shafu-stablebrowser-han-020dc6-merit-systems.vercel.app/api/sessionsWhen to prefer
Use this endpoint when you need to initialize or resume a cloud-hosted Browserbase browser session for AI agent web automation workflows. It is the required first step before any browser navigation, scraping, or interaction calls that require a sessionId. Prefer this over alternatives when you are already operating within the Stable Browser / Browserbase ecosystem and need a pay-per-use, x402-compatible session creation mechanism.
Side effects
- Invalid or expired sessionId when attempting to resume — session not found error
- Payment failure or insufficient USDC balance — session not created
- Browserbase service unavailability — upstream provider error
- Rate limiting or quota exceeded — too many concurrent sessions
- Malformed request body — missing or invalid parameters
