Tickets are one-use, one controlling stream is allowed per session, origins are validated, frames are bounded to 8 MiB, and ownership, permission, entitlement, and session state are rechecked every 30 seconds. ## OpenAPI ````yaml https://api.infrawatch.com/openapi.json?contract=d15375c get /projects/{project_uuid}/sessions/{session_uuid}/stream openapi: 3.1.0 info: description: >- Customer-facing Infrawatch APIs. Authenticate with an API key unless an operation documents another supported credential. ### Infrawatch Public API Public API authenticated exclusively with Infrawatch API keys. ### Infrawatch Customer Alerting API Project alert rules, destinations, silences, inbox state, and delivery history. ### Infrawatch Remote Browser API Project-scoped interactive browser sessions owned by Platform Core. Session admission, lifecycle, RBAC, audit, usage, screenshot history, and stream tickets are Platform Core resources. The browser master is private infrastructure and its identifiers, proxy routes, process options, and credentials are never exposed by this API. A session and all of its evidence are private to the credential that created it. Project managers may list project session metadata, inspect one session's metadata, and terminate it, but cannot access its live stream, screenshots, or network events. Terminal session metadata and screenshots are retained indefinitely. A creator can replay a terminal session as a new queued resource while preserving a durable link to the source session. ### Infrawatch ESI API Customer-facing External Surface Intelligence API for project-scoped product data authenticated by an Infrawatch API key. API keys are constrained to their immutable owner's project ceiling and assigned ESI scopes; human project-manager fallback never expands an API key. Authorised API-key requests are rate-limited and consume monthly quota. ### Infrawatch Reports API Threat report discovery API authenticated by an Infrawatch API key. ### Infrawatch Public Rules API Account-aware rule authoring, taxonomy, catalogue, and runtime observations for API clients. ### Infrawatch Search API Search hosts, services, DNS records, and certificates. Complete percent-encoded query strings are limited to 65536 bytes. title: Infrawatch Customer API version: 1.0.0 servers: - description: Infrawatch customer API url: https://api.infrawatch.com/api/v1 security: [] tags: - name: API Usage - name: Projects - name: Alert destinations - name: Alert rules - name: Alert silences - name: Alerts - name: Browser sessions - name: Browser evidence - name: Browser streaming - name: Access - name: Inventory - name: Dangling DNS - name: Findings - name: Secrets - name: Typosquatting - name: Services - name: AI Surface - description: Search hosts, services, DNS records, certificates, and open directories. name: Search - name: Dashboard - name: Reports - name: Rules - name: Rule tags - name: Rule observations paths: /projects/{project_uuid}/sessions/{session_uuid}/stream: servers: - url: https://api.infrawatch.com/api/v1 get: tags: - Browser streaming summary: Upgrade to the controlling browser WebSocket. description: | Supply the exact `subprotocol` returned by the stream-ticket endpoint in `Sec-WebSocket-Protocol`.
