Install the SDK - Sayless

Requirements

Node.js 18+ (uses global fetch)
A personal API key (sl_api_…) or OAuth access token (sl_oat_…) from Settings → API

Install

npm install @sayless/sdk
# or
yarn add @sayless/sdk
# or
pnpm add @sayless/sdk

The package lives in the Sayless monorepo at app-mlp/packages/sdk and is generated from the gateway OpenAPI contract.

Authenticate

import { SaylessClient } from '@sayless/sdk';

const sayless = new SaylessClient({
  apiKey: process.env.SAYLESS_API_KEY,
  // or: accessToken: process.env.SAYLESS_ACCESS_TOKEN,
  apiUrl: process.env.SAYLESS_API_URL, // optional; defaults to https://api.sayless.ai
});

Never commit keys. Prefer environment variables in CI and local .env files that stay gitignored.
