1 / 2Overview
What is Zerg Router?
Run DeepSeek in Codex.
Zerg Router is one OpenAI-compatible endpoint for all your coding agents. The routing policy lives in your account, not inside each tool: run DeepSeek 4.1 Flash (or other models) inside Codex and keep your workflow, give every API key its own daily budget enforced per request, set explicit fallbacks (on a 5xx, 429, or timeout, try your next model), and see remaining weekly quota and reset dates across Codex accounts.
Creating a Zerg identity, Router keys, and Codex account monitoring is free; new accounts get a no-card DeepSeek trial. Paid usage is billed monthly with no monthly base fee — $0.30/1M input tokens, $0.03/1M cached input, $1.20/1M output — or bring your own provider keys.

Zerg Router Key Features
One endpoint, many routes
A single OpenAI-compatible Router endpoint (zergrouter.com/v1) connects all your coding tools — Codex, OpenCode, Pi, ZTC — with model choice per client.
DeepSeek in Codex
Run DeepSeek 4.1 Flash inside Codex and compatible agents via the Router, with a no-card $1 trial for eligible new accounts.
Per-key daily budgets
Every API key gets its own daily budget enforced per request, so spend is controlled rather than discovered on the invoice.
Codex capacity tracking
See remaining weekly quota and reset dates across all connected Codex accounts in one dashboard.
Explicit fallbacks
On 5xx, 429, or timeout the Router tries your next configured model, with an authenticated model catalog as the source of truth.

Common questions
Zerg Router FAQs
How do I start using it?
Sign in, create a Router key, and point your coding tool at zergrouter.com/v1 — check GET /v1/models with your key to see available routes first.
Do I need my own DeepSeek or provider keys?
No — platform-funded DeepSeek access needs no separate credential; paid usage just requires a card and is billed monthly with no base fee.
Does it use up my ChatGPT/Codex subscription?
No — a Codex subscription is separate from Router usage; platform-funded DeepSeek doesn't spend your ChatGPT or Codex quota.
Can I connect my Claude subscription?
No — Anthropic API credentials and Claude subscriptions are separate; the Anthropic view only records manual quota readings.
