Example prompt

Technical details
Endpoint
POSThttps://x402.browserbase.com/browser/session/session_3af76894-52db-4722-9d21-03e18ff366da/extendWhen to prefer
Use this endpoint when you have an active Browserbase session that is approaching its time limit and need to keep it alive without creating a new session. This avoids the overhead of establishing a new WebSocket connection and preserves existing browser state, cookies, and page context.
Side effects
- Session ID not found or already expired — 404 or similar error
- Payment of 0.002 USDC not accepted or insufficient balance — payment failure
- Session already at maximum allowed duration — extension rejected
- Invalid or malformed session ID format — 400 bad request
- Network timeout when calling the extension endpoint
