Installation

.NET

# Via NuGet (when published)
dotnet add package SerialMemory.Client

# Or reference local project
dotnet add reference path/to/SerialMemory.Client.csproj

Node.js

# Via npm (when published)
npm install @serialmemory/client

# Or link local package

cd your-project && npm link @serialmemory/client

Basic Usage

.NET

using SerialMemory.Client;

var client = new SerialMemoryClient(new SerialMemoryOptions
{
    BaseUrl = "http://localhost:5000",
    ApiKey = "your-api-key"
});

// Search
var results = await client.SearchAsync("query");

// Ingest
var memory = await client.IngestAsync("Content to remember");

// User persona
var persona = await client.GetUserPersonaAsync();

Node.js / TypeScript

import { SerialMemoryClient } from '@serialmemory/client';

const client = new SerialMemoryClient({
  baseUrl: 'http://localhost:5000',
  apiKey: 'your-api-key'
});

// Search
const results = await client.search('query');

// Ingest
const memory = await client.ingest('Content to remember');

// User persona
const persona = await client.getUserPersona();

Error Handling

Both SDKs provide typed exceptions:

Exception	HTTP Code	Description
RateLimitExceededError	429	Too many requests, retry after delay
UsageLimitExceededError	402	Plan quota exhausted
AuthenticationError	401/403	Invalid credentials
CircuitBreakerOpenError	N/A	Service temporarily unavailable

Examples

Each SDK includes example projects:

• Personal Assistant - AI second brain pattern
• Project Memory - Multi-project isolation

See examples/ for standalone example projects.
