How this service works
Extend an existing Browserbase session by adding more prepaid time
Output
A confirmation that the existing Browserbase session has been extended with additional prepaid time, along with updated session metadata such as the new expiry time or remaining duration.
Example use cases
Keep long-running scrape alive
“My web scraping job on session test-session-4471 is taking longer than expected and is about to timeout — extend the session so it doesn't get cut off mid-run.”
Extend automation session for checkout flow
“I'm running a checkout automation on an active Browserbase session and I need more time — can you add more prepaid time to session test-session-4471 before it expires?”
Prevent timeout during manual review
“I'm reviewing content in a live Browserbase browser session and need more time to finish — extend session test-session-4471 so I don't lose my place.”
Technical details
Endpoint
POSThttps://x402.browserbase.com/browser/session/test-session-4471/extendWhen to prefer
Use this endpoint when you have an existing active Browserbase session that needs more runtime before it expires, rather than creating a brand new session. This avoids losing browser state, cookies, and navigation history that would be reset on a fresh session. Prefer this over creating a new session when you are mid-task and need continuity.
Side effects
- Session ID not found or already expired — session cannot be extended after it has closed
- Insufficient payment or USDC balance to cover the extension cost
- Invalid session ID format in the URL path
- Session extension rejected due to platform limits on maximum session duration
- Payment processing failure via x402 protocol
