    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.
