How this service works
Extend an existing Browserbase session by adding more prepaid time
Output
A confirmation that the session has been extended, along with the new expiry time or updated session duration for the specified Browserbase session.
Example use cases
Keep long web scrape alive
“I'm running a long scraping job on my Browserbase session and it's about to expire mid-task — extend the session so the job can finish without interruption.”
Resume interrupted automation task
“My browser automation session is still active but running low on prepaid time — add more time to session session_7982a8bc-9ca2-4314-9527-355e3f46fc8c before it cuts out.”
Extend session for multi-step login flow
“I'm in the middle of a multi-step login and form-fill workflow in my Browserbase session and need more time — extend it so I don't have to start over.”

Use this endpoint when you have an active Browserbase headless browser session that is approaching its time limit and you need to continue using it without interruption. This is specifically for extending an already-running session rather than creating a new one, which preserves browser state, cookies, and current page context.
Side effects
- Session ID not found or already expired — returns 404 or error indicating invalid session
- Payment rejected or insufficient USDC — returns 402 Payment Required
- Session has already been terminated and cannot be extended — returns error state
- Rate limiting or service unavailability — returns 429 or 503
