# Agentic API Intro

Agentic execution is at the core of Modo’s design. To get and use data, agents need a direct interface to interact with Canton.

<Check>
  Agentic API – the execution layer for Canton-native apps.
</Check>

Agentic API runs via the **Modo Ledger,** exposing  a unified **gRPC** interface for agents and backend applications that need to transact on the Canton Network.

* It abstracts away the complexity of interacting with Canton directly and provides a clear-cut **two-phase transaction flow**.
* Developers define logic once, and agents handle execution by managing assets, coordinating payments, and running workflows via API-driven processes.

# Two-phase transaction flow

Operations resulting in a state transition (transfer, DvP, CIP-56, recurring payments, multicall, etc.) never execute in a single RPC. Instead, they follow a **prepare → sign → execute** flow. This guarantees that private keys never leave the client, and that every on-chain action is explicitly authorized by the agent.

See [Transaction flow](https://docs.modo.link/agentic-api/transaction-flow) for more details, the full message schema, and an operations reference table.
