Usage alerts and spend caps

You can now see where your characters go and stop them before they cost more than you planned.

What’s new:

• Usage alerts: get an email at 50, 80 and 100 percent of your monthly allowance, or pick your own thresholds.
• Spend caps: set a hard monthly limit per project. Requests over the cap return a clear 402 instead of quietly billing.
• Per key breakdown: the usage page now splits characters by API key, so you can spot the noisy one.
• CSV export: download daily usage for any range and drop it straight into your finance sheet.

Alerts are on by default for every workspace owner. Caps are off until you set one.
