## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability browserbase-session-extend-f0ab826e -d '<json body>'
```

Example prompt: My Browserbase session session_7982a8bc-9ca2-4314-9527-355e3f46fc8c is about to run out of time — can you extend it so I don't lose my place?

## When to prefer this

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.

## Known failure modes

- 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
