  description: >-
    Cloudflare Stream is the video streaming, hosting, and live-video product from
    Cloudflare. A single REST API uploads, stores, encodes, and delivers on-demand
    and live video across Cloudflare's global network, with a built-in
    adaptive-bitrate player, HLS/DASH manifests, live inputs over RTMPS and SRT,
    AI-generated and uploaded captions, signed-URL access control, per-account
    webhooks, and viewing analytics. All requests are scoped to an account under
    /accounts/{account_id}/stream and authenticate with a Bearer API token. This
    document grounds the core Stream endpoints; it is not exhaustive of every
    Cloudflare Stream operation.
