@solrouter/sdk

Privacy-first AI API client with end-to-end encryption.

Installation

npm install @solrouter/sdk

Quick Start

import { SolRouter } from '@solrouter/sdk';

const client = new SolRouter({
  apiKey: 'sk_solrouter_your_key_here'
});

// Your prompt is encrypted client-side before being sent
const response = await client.chat('Explain quantum computing');
console.log(response.message);

How It Works

1. Client-side Encryption: Your prompt is encrypted using Arcium's RescueCipher before leaving your device
2. Blind Backend: The server only sees encrypted data - it cannot read your prompt
3. TEE Processing: Decryption only happens inside a Trusted Execution Environment (hardware-isolated)
4. Encrypted Response: The AI response is encrypted back to you

API Reference

new SolRouter(config)

Create a new SolRouter client.

const client = new SolRouter({
  apiKey: 'sk_solrouter_...',  // Required: Your API key
  baseUrl: 'https://...',       // Optional: Custom API URL
  encrypted: true,              // Optional: Enable encryption (default: true)
});

client.chat(prompt, options?)

Send a chat message.

const response = await client.chat('Hello!', {
  model: 'gpt-oss-20b',         // Model to use
  encrypted: true,               // Override encryption setting
  systemPrompt: 'You are...',    // System prompt
  chatId: 'conv-123',            // For multi-turn conversations
  useRAG: false,                 // Enable knowledge retrieval
  useLiveSearch: false,          // Enable web search
});

console.log(response.message);        // AI response
console.log(response.encrypted);      // Was request encrypted?
console.log(response.usage);          // Token usage
console.log(response.cost);           // Cost in USDC

Available Models

| Model | Description | |-------|-------------| | gpt-oss-20b | Open-source GPT 20B (default, cheapest) | | qwen3-8b | Qwen 3 8B parameters | | gemini-flash | Google Gemini Flash | | claude-sonnet | Anthropic Claude Sonnet | | gpt-4o-mini | OpenAI GPT-4o Mini |

client.getBalance()

Check your account balance.

const balance = await client.getBalance();
console.log(balance.balanceFormatted); // "$10.5000"

Pricing

| Model | Input (per 1M tokens) | Output (per 1M tokens) | |-------|----------------------|------------------------| | gpt-oss-20b | $0.15 | $0.30 | | qwen3-8b | $0.05 | $0.10 | | gemini-flash | $0.075 | $0.30 | | claude-sonnet | $3.00 | $15.00 | | gpt-4o-mini | $0.15 | $0.60 |

Privacy Guarantee

When encryption is enabled (default):

• Your prompts are encrypted on your device using Arcium's MPC encryption
• The SolRouter backend NEVER sees your plaintext prompts
• Decryption only happens inside a hardware-isolated TEE
• On-chain privacy attestations are available for verification
