# Mark an event on the app charts

    Self hosted ASO toolkit API.


    A metered instance carries RateLimit-Limit, RateLimit-Remaining and
    RateLimit-Reset on every response, for the tightest limit the request
    touched. A self hosted instance has no request rate limits and sends no such
    header. Limits are per workspace, so minting more tokens does not buy more
    capacity, and they are sized per plan across three classes: read for stored
    data, write for configuration changes and store for the endpoints that reach
    the App Store or Google Play.


    A 429 carries Retry-After and a rateLimit object naming the window that
    closed, or an aiAllowance object when the workspace has spent the AI calls
    its plan includes this month. A 403 with a quota object means a plan
    capacity limit such as apps or tracked keyword markets, which is a different
    problem from a rate limit. A 402 with an entitlement object means the
    workspace needs a plan.


    Positions are 1-based and null means checked but not found within the
    captured depth, never zero. Daily granularity uses UTC dates.
