summary: >-
  AllTick has a genuine, production, push-based event surface — two WebSocket streams delivering
  tick-by-tick trades and order-book depth — but ships NO machine-readable event contract for it.
  The protocol is fully specified in prose (numbered cmd_id messages, request/response/push triples,
  a mandatory heartbeat) and completely absent from every machine-readable artifact: the OpenAPI
  covers only the 12 HTTP operations, and no AsyncAPI document exists on any host. This is a
  streaming-first market-data vendor whose streaming half is invisible to tooling.
asyncapi:
  present: false
  probed:
    - url: https://quote.alltick.co/asyncapi.json
      status: 401
    - url: https://en.apis.alltick.co/asyncapi.yaml
      status: 404
    - url: https://apis.alltick.co/api-reference/openapi.json
      status: 200
      note: the only machine-readable contract; HTTP only, no `webhooks` block, no callbacks
  note: >-
    quote.alltick.co returns its token gate ({"msg":"token is required","ret":401}) for every path,
    so a 401 there is a gate, not a hidden document.
webhooks:
  customer_registerable: false
  openapi_webhooks_block: false
  openapi_callbacks: false
  note: >-
    AllTick never calls a customer URL. Delivery is pull (HTTPS) or client-initiated subscribe-and-
    receive (WebSocket). No `type: Webhooks` pointer is emitted, because AllTick advertises no
    webhook surface and claiming one would be false.

not_supported:
  - name: K-line push
    detail: >-
      AllTick states explicitly that the WebSocket interface does NOT push candlesticks; both
      historical and real-time K-lines are HTTP-only.

pointer_note: >-
  Neither an `AsyncAPI` nor a `Webhooks` pointer is emitted in apis.yml. The event surface is real
  and this artifact documents it faithfully, but AllTick publishes no AsyncAPI document and no
  webhooks; asserting either would credit a contract that does not exist. Publishing an AsyncAPI 3.0
  document for these two channels is the highest-value single artifact AllTick could add.
