Webhook (Notify API) and WebSocket WebSocket Subscriptions on Alchemy are priced based on bandwidth: the amount of data delivered as part of the subscription.
Each subscription type is priced identically, per byte:
On average, a typical webhook or WebSocket subscription event is about 1000 bytes, so would consume 40 compute units. Note that this can vary significantly based on the specific event delivered Subscription API Quickstart
| Error | Compute Units |
