A request is a single successful JSON-RPC call to a node through an HTTPS or WebSocket Secure endpoint.
A request is considered successful and consumed in the following cases:
- HTTP: the server returns 200
- WebSocket: the server sends a message
For example, sending an eth_getLogs request over HTTP will return all events specified in the request and count as one request.
Sending an eth_subscribe request over WebSocket will subscribe to events in real time and each event sent will count as one request.
