How this service works
Extend an existing Browserbase session by adding more prepaid time
Output
Returns confirmation that the session has been extended with updated expiry time and remaining prepaid duration for the specified session ID.
Example use cases
Long-running web scraping job
“My scraper is still running on Browserbase session xyz789 and it's going to need at least 15 more minutes — can you extend the session so it doesn't get cut off?”
Agent mid-task browser session renewal
“I have an active Browserbase session with ID sess_abc456 that's running out of time while my agent is filling out a multi-step form — extend it by 20 minutes please.”
Automated test suite running long
“Our end-to-end test suite on Browserbase session id def012 is taking longer than expected — add another 30 minutes of time to the session so the tests can finish.”
Technical details
Endpoint
POSThttps://x402.browserbase.com/browser/session/:id/extendWhen to prefer
Use this endpoint when you have an active Browserbase session that is approaching its prepaid time limit and you need to continue using it without interruption. This is the only way to extend an existing session's duration rather than creating a new one and losing the current browser state, cookies, and navigation context.
Side effects
- Session ID not found or already expired — 404 error
- Insufficient payment or payment processing failure — 402 error
- Session has already reached maximum allowed duration
- Invalid session ID format in path parameter
- Session already terminated by user or system
