Each entry reports whether a call is running on it and, for named executors, the target ID and URL of the tab it owns. Returns 404 for a browser whose image predates executors. ## OpenAPI ````yaml https://api.onkernel.com/spec.json get /browsers/{id_or_name}/playwright/executors openapi: 3.1.0 info: description: Developer tools and cloud infrastructure for AI agents to use web browsers title: Kernel API version: 0.1.0 servers: - description: API Server url: https://api.onkernel.com security: - bearerAuth: [] tags: - description: Search the web and retrieve content for selected results. name: Search - description: Create and manage browser sessions. name: Browsers - description: Control mouse, keyboard, and screen on the browser instance. name: Browser Computer Controls - description: >- Execute Playwright code against the browser instance and manage the executors it runs in. name: Browser Playwright - description: Execute JavaScript in the browser instance's persistent Browser REPL. name: Browser REPL - description: Discover and invoke native page tools across the browser instance. name: Browser WebMCP - description: Read, write, and manage files on the browser instance. name: Browser Filesystem - description: Execute and manage processes on the browser instance. name: Browser Processes - description: Record and manage browser session video replays. name: Browser Replays - description: Stream logs from the browser instance. name: Browser Logs - description: >- Stream live telemetry events from a browser session, and manage the destinations sessions export them to. name: Browser Telemetry - description: Create, list, retrieve, and delete browser profiles. name: Profiles - description: Create and manage proxy configurations for routing browser traffic. name: Proxies - description: Create, list, retrieve, and delete browser extensions. name: Extensions - description: Create and manage browser pools for acquiring and releasing browsers. name: Browser Pools - description: Inspect the identity and authorization context for the current request. name: Authentication - description: >- Create and manage auth connections for automated credential capture and login. name: Managed Auth - description: Create and manage credentials for authentication. name: Credentials - description: Configure external credential providers like 1Password. name: Credential Providers - description: List applications and versions. name: Apps - description: Create and manage app deployments and stream deployment events. name: Deployments - description: Invoke actions and stream or query invocation status and events. name: Invocations - description: Read and manage organization-level limits. name: Organization - description: | Create and manage projects for resource isolation within an organization.
