Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-creator-41dfccfe -d '<json body>'
```

Example prompt: Start a new Browserbase cloud browser session for me so I can begin automating a web task — I don't have an existing session to resume.

## When to prefer this

Use this endpoint when you need to initialize or resume a remote cloud browser session backed by Browserbase, especially within a paid x402-compatible agentic workflow where each browser session is billed at $0.10 USDC. Prefer this over self-hosted headless browser setups when you need a managed, scalable cloud browser without infrastructure overhead.

## Known failure modes

- Invalid or expired sessionId provided for resume — session not found
- Payment failure — insufficient USDC balance for $0.10 session fee
- Browserbase capacity unavailable — service temporarily at limit
- Malformed request body — unexpected field types
- Session creation timeout — upstream Browserbase error

## How this service works

Create a new browser session ($0.10). Optionally pass sessionId to resume an existing Browserbase session. Returns sessionId (Browserbase session ID) to use for all subsequent calls.

## Output

Returns a sessionId string representing the newly created (or resumed) Browserbase session, which must be passed to all subsequent browser automation API calls in this workflow.
