Tiers and variables

Subscriptions

After sign-in, the SDK keeps a snapshot of the user’s active subscriptions. Reading it never touches the network, so it is safe in paint handlers.

if (eonauth::HasTier("Pro")) { /* … */ }

if (auto pro = eonauth::FindTier("Pro")) {
    // pro->expiresAt is unix seconds; 0 means lifetime
    statusBar.SetText(eonauth::ToWide("Pro until " + eonauth::FormatTime(pro->expiresAt)));
}

if (eonauth::HighestLevel() >= 2) { /* level 2 or above */ }   // -1 with no subscriptions

for (const eonauth::Subscription& s : eonauth::Subscriptions()) { /* highest level first */ }

The snapshot is refreshed by every heartbeat and redeem. When it changes, the SDK raises Event::SubscriptionsChanged, so re-run your tier checks there.

Caution

HasTier is a local check. A patched binary can make it return true. Use it to decide what the UI shows, and put the valuable part behind a variable or file the server only gives to that tier.

Variables

A variable is fetched one at a time, by ID. Copy the ID (var_…) from the panel’s Variables page.

eonauth::FetchVariableAsync("var_0123456789abcdef0123456789abcdef",
    [](const eonauth::Result& r, const std::string& value) {
        if (r) UseValue(value);
        else if (r.status == eonauth::Status::VariableNotFound) ShowUpgradePrompt();
        else ShowError(eonauth::UserMessage(r), eonauth::UserHint(r));
    });

// Later, without the network: the last value fetched in this session.
if (auto v = eonauth::Variable("var_0123456789abcdef0123456789abcdef")) { /* *v */ }

• There is deliberately no way to list variables. A client can only read the IDs you compiled in.
• An unknown ID and an ID locked to tiers the user doesn’t have both give VariableNotFound.
• Values are text up to 128 KB. Binary content belongs in files.
• Free mode sessions can read only variables marked Free users.
• The cached value is cleared when the session ends.

What to put in variables

Anything a cracked copy shouldn’t have just by skipping a check: a download link for the Pro build, the configuration a premium feature needs, a key for your own backend, rule tables. If the feature can’t work without the value, skipping the check doesn’t help.
