SDK Gateway
ARCHITECTURE OVERVIEW

How It Works

A single HTTP endpoint that streams responses from multiple AI SDKs

Request

POST /api/v1/agent/run
{
"prompt": "Build a REST API",
"sdk": "claude",
"options": {
"model": "claude-sonnet-4-5"
}
}

Streams SSE

// Server-Sent Events
data: {""type": "assistant",
"data": {...},
"sdk": "claude"}
data: {""type": "result",
"data": {...},
"sdk": "claude"}
SDK OPTIONS

Fine-grained control over each SDK

Claude Agent

  • Model selection (Sonnet, Opus, Haiku)
  • Tool permissions (Read, Write, Edit, Bash, etc.)
  • Permission modes (default, acceptEdits, bypassPermissions)
  • Session resume/fork capabilities
  • Custom system prompts

Codex Agent

  • Sandbox modes (read-only, workspace-write, full-access)
  • Full auto mode for autonomous execution
  • Structured JSON output with schema validation
  • Thread continuation support

FAQ

Common questions

Can I modify the code?

Yes. Full source code with MIT-style license for commercial use. Modify, extend, and build upon it however you need.

What about new SDKs?

The factory pattern makes adding new providers straightforward. Pro tier includes updates for new SDK integrations for one year.

Do I need the CLI tools installed?

Yes. The service wraps Claude Code CLI and Codex CLI. Installation is one npm command each: npm install -g @anthropic-ai/claude-code and npm install -g @openai/codex

Is it production-ready?

Yes. Stateless design, proper error handling, async patterns, and clean architecture throughout. Built for horizontal scaling from day one.
