Low-credit alerts
When a request leaves your balance under your threshold, Hyperouter sends one notice: an email, a banner in the dashboard, and a credits.low event to every webhook endpoint subscribed to it. The alert fires once per crossing and arms again when a top-up brings the balance back to the threshold.
The default threshold is $5. Set your own, or 0 to turn the alert off, on the Credits page of the dashboard.
The event carries the account id, like other webhook events. Fetch the balance with GET /v1/credits.
