  APITube publishes no AsyncAPI document (probed apitube.io/asyncapi.json 404,
  api.apitube.io/asyncapi.json 401-gated edge), but ships a real, well-documented event surface
  with three delivery channels. Captured here as a webhook/streaming catalog; type: Webhooks.
channels:
- name: webhooks
  kind: push (HTTP POST to a registered URL)
  event: articles.new
  management: dashboard only (https://dashboard.apitube.io/webhooks) — a webhook is a saved query with a destination, filtered with the same parameters as /v1/news/everything
  payload: '{event: "articles.new", webhook_id, delivered_at, articles[]} — up to 100 articles per delivery, same article shape as /v1/news/everything'
  security:
    signature_header: 'X-Webhook-Signature: sha256=<hmac>'
    scheme: HMAC-SHA256 over timestamp + "." + rawBody with a per-webhook signing secret shown once at creation
  headers: [X-Webhook-Signature, X-Webhook-Id, X-Webhook-Delivery-Id, X-Webhook-Timestamp]
  delivery: any 2xx acknowledges; non-2xx or 30s timeout schedules automatic retries with exponential backoff; full delivery logs in the dashboard
