Used at task handoff and while the user has the session open, so a cloud session that resumes to about:blank can be restored to the tabs the user actually had open. When `tabs` is omitted the sandbox captures the live set itself from the session's daemon. Tab URLs never leave the user's sandbox. ## OpenAPI ````yaml https://neo.api.projectdiscovery.io/api/openapi.json post /api/v1/browser/sessions/{session_ref}/tabs openapi: 3.1.0 info: contact: name: ProjectDiscovery url: https://neo.projectdiscovery.io description: Neo API Server - Security agent orchestration platform license: name: Apache 2.0 url: https://www.apache.org/licenses/LICENSE-2.0 title: Neo API version: 1.0.0 servers: - description: Production url: https://neo.api.projectdiscovery.io - description: Development url: https://neo.api.dev.projectdiscovery.io - description: Local development url: http://localhost:8080 security: [] tags: - description: Task execution and management name: Tasks - description: Agent listing and management name: Agents - description: Public agent directory name: Agent Directory - description: User file storage management name: Files - description: User working memory management name: Memory - description: Scheduled and recurring task management name: Schedules - description: Knowledge base and semantic search name: Knowledge - description: Encrypted user credentials and API keys name: Secrets - description: Neo API key management for programmatic access name: API Keys - description: User profile and account information name: User - description: Task and LLM usage tracking name: Usage - description: Bring Your Own Key provider management name: BYOK - description: Model discovery and capabilities name: Models - description: Third-party integrations name: Integrations - description: Skill knowledge documents for agent prompts name: Skills - description: Team management and member invitations name: Teams - description: Prompt library management and discovery name: Prompts - description: Slack bot integration for workspace installation and OAuth name: Slack - description: GitHub integration for PR reviews and repository management name: GitHub - description: Vulnerability issue tracking and management name: Issues - description: Subscription billing and plans name: Billing - description: Project management and member assignments name: Projects - description: SSH key pair generation and management for remote server access name: SSH Keys - description: Codebase structural analysis and mapping name: Codemaps - description: AI-generated codebase documentation and security analysis name: CodeWiki - description: Captured HTTP traffic query and replay name: Network Events - description: Vulnerability triage for HackerOne, GitHub, and Security Inbox name: Triage - description: >- Application-internal endpoints used by the Neo UI.
