Proxy CommandCode

A transparent reverse proxy that translates OpenAI-compatible requests (/v1/chat/completions) into CommandCode's internal endpoint (/alpha/generate), then returns responses in OpenAI format your editor understands.

Use any CommandCode model (including the Go plan) with ZCode, 9router, Cursor, Continue, Aider, and any editor that supports custom OpenAI endpoints.

Why

CommandCode has two API surfaces:

Endpoint	Plan required
/provider/v1/chat/completions	Provider plan
/provider/v1/messages	Provider plan
/alpha/generate	Any plan (Go included)

This proxy speaks the same envelope the official CLI uses, so it works on any plan.

How it works

Editor → POST /v1/chat/completions (OpenAI format)
  → Proxy translates to CommandCode format
    → POST api.commandcode.ai/alpha/generate
  ← Proxy translates NDJSON stream back to OpenAI SSE/JSON
← Editor receives standard OpenAI response

Quick start

git clone https://github.com/nasrulhadi/proxy-commandcode.git
cd proxy-commandcode
node server.js
# → listening on http://localhost:3456

Zero dependencies. Node.js 18+ only.

Get your token

1. Go to https://commandcode.ai/settings/billing
2. Copy your user_... token
3. Use it as the API key in your editor

Env vars

Variable	Default
PCMC_PORT	3456
PCMC_VERSION	1.54.0
PCMC_DEBUG	off (set 1 to enable)

Enabling debug mode

PowerShell:

$env:PCMC_DEBUG="1"; node server.js

Command Prompt:

set PCMC_DEBUG=1 && node server.js

macOS / Linux / WSL:

PCMC_DEBUG=1 node server.js

When enabled, raw upstream responses are dumped to dump/ for troubleshooting.

Integration

9router

{
  "commandcode": {
    "base_url": "http://localhost:3456/v1",
    "api_key": "user_xxxxxxxxxx",
    "models": ["deepseek/deepseek-v4-pro", "moonshotai/Kimi-K2.5"]
  }
}

ZCode

Set custom OpenAI endpoint in settings:

• Base URL: http://localhost:3456/v1
• API Key: your user_... token
• Model: deepseek/deepseek-v4-pro

Cursor

Settings → OpenAI API Key → Override Base URL: http://localhost:3456/v1

Continue (VS Code)

{
  "models": [{
    "title": "DeepSeek V4 Pro",
    "provider": "openai",
    "apiBase": "http://localhost:3456/v1",
    "apiKey": "user_xxxxxxxxxx",
    "model": "deepseek/deepseek-v4-pro"
  }]
}

Aider

aider --openai-api-base http://localhost:3456/v1 \
      --openai-api-key user_xxxxxxxxxx \
      --model openai/deepseek/deepseek-v4-pro

Other editors

Any editor with custom OpenAI endpoint support works the same way: point base URL to http://localhost:3456/v1, use your token as API key.

Available models

Model availability depends on your CommandCode plan:

Plan	Price/mo	Access
Go	$1	Open-source + free + some premium (Luna, Grok 4.5, Muse Spark Contributor)
GOAT	$10	Go + per-model premium allowances (Sol, Grok 4.6, Muse Spark, Gemini 3.7/3.8)
Pro	$20	GOAT + full premium (GPT-6, Claude, Gemini)

Free models (cost no credits):

Logs

All requests are logged to both terminal (colorized) and proxy.log (plain text):

[2026-07-09T09:10:06.092Z] [req] tencent/Hy3 | ::1 | sync | 232 bytes
[2026-07-09T09:10:07.137Z] [upstream] 200 OK | tencent/Hy3 | 1045ms
[2026-07-09T09:10:09.303Z] [done] tencent/Hy3 | 92 text / 0 tools | stop | 3211ms

Color legend (terminal only):

• [req] — cyan — incoming request with model, client IP, stream mode, byte size
• [upstream] — green — HTTP status, model, latency to CommandCode
• [done] — bold — text / reasoning / tool counts, finish reason, total duration
• [error] — yellow — upstream or internal errors

Log fields:

• text / reasoning — total characters of each type in the response
• tools — number of tool calls the model made
• reason — stop (finished) or tool_calls (waiting for tool results)

Common errors

Log	Fix
[upstream] 401	Token invalid. Get a fresh one from billing.
[upstream] 400	Request format mismatch. Check proxy version.
[upstream] timeout	Upstream took >5 min. Retry.
[error] context length	Prompt too large for model (e.g. ~520K tokens vs 256K max). Reduce messages or switch to a higher-context model.
EADDRINUSE	Proxy auto-kills the old process on start.
