|
|
//!
|
||
|
|
//! Implements a TollGate-inspired protocol for paying for streaming data
|
||
|
|
//! using Cashu ecash micropayments. Supports three metering models:
|
||
|
|
//!
|
||
|
|
//! - **Bytes**: Pay per MB downloaded (content, federation sync)
|
||
|
|
//! - **Time**: Pay per minute of access (relay, API endpoints)
|
||
|
|
//! - **Requests**: Pay per API call
|
||
|
|
