Via SDK

Interact with Nesa Chain via the official SDK

Nesa provides a developer-friendly Node.js SDK for executing inference requests in both client and server environments.

Official SDK URL: https://github.com/nesaorg/nesa.js

Overview

In this section, we cover high-level SDK usage information; on the other hand, detailed documentation can be found in README.md.

1. SDK Initialization

Interactions with a specific kernel are performed via a ChatClient instance. To create an instance, pass your desired configuration parameters, such as modelName, lockAmount, and chainInfo, to the constructor.

lockAmount specifies the maximum amount of unes (0.000001 NES) to pay during the inference process. This amount is deducted immediately, with any unused portion refunded following the interaction.

2. Session Creation

Establishing a session confirms your unes lockup via a blockchain transaction. Complete this process with a call to the ChatClient instance's requestSession method.

3. Request & Response

This process takes place over a websocket connection for speedy, two-way interaction.

Begin your single- or multiple-message interaction with the configured kernel by using the ChatClient instance's requestChat method, passing it input via the messages field.
