# Real-Time API

# Live Data on Canton

**Modo Real-Time API** continuously streams live Canton network data over [gRPC](https://docs.silvana.one/sdk/grpc-api/grpc-api-types), delivering on-chain events (transactions, updates, etc.) as they happen.

Real-Time API is especially helpful for building interfaces and backend systems that need a live view of data, where timing is critical:

* Live network dashboards;
* Monitoring and alerting systems;
* Automated backend workflows;
* Portfolio and activity trackers;
* Analytics pipelines powered by always-fresh data;
* and more...

# Why It Stands Out

* **True real-time delivery** – receive transactions, updates, and network events the moment they happen;
* **Millisecond-speed access** – power latency-sensitive apps with ultra-fast data delivery;
* **Streaming, not polling** – skip repeated requests and outdated refresh cycles;
* **Easy to use** – plug in [gRPC](https://docs.silvana.one/sdk/grpc-api/grpc-api-types), authenticate, and start building straight away;
* **No infrastructure needed** – get the speed and reliability you need without becoming a validator or supervalidator on Canton.

# Methods

Developers can follow ledger progress, balances, active contracts, updates, rates, and preapproval data through dedicated streaming methods.
