Gpt2api Openai Gateway
This is a self-hosted gateway that reverse-engineers chatgpt.com to expose GPT Image 2 and DALL·E 3 through standard OpenAI API endpoints. You get multi-account pooling, proxy rotation, rate limiting, and a billing dashboard, all packaged in Docker Compose with MySQL and Redis. The main appeal is turning ChatGPT's image generation into something you can call from the OpenAI SDK without dealing with web sessions manually. It handles account rotation automatically and includes img2img edits via multipart uploads. Setup requires generating AES keys for encrypting stored tokens and adding ChatGPT accounts via JSON import. If you need batch image generation at scale or want to abstract away ChatGPT account management, this does the plumbing work.

gpt2api OpenAI Gateway
Skill by ara.so — Daily 2026 Skills collection.
gpt2api is a self-hosted OpenAI-compatible API gateway that reverse-engineers chatgpt.com to expose GPT Image 2 / DALL·E 3 / IMG2 grayscale capabilities via standard /v1/images/generations, /v1/images/edits, and /v1/chat/completions endpoints. It provides multi-account pooling, proxy pooling, rate limiting, credit billing, and an admin dashboard.
Installation & Deployment
Docker Compose (Recommended)
git clone https://github.com/432539/gpt2api.git
cd gpt2api/deploy
cp .env.example .env
Edit .env — these three are required:
JWT_SECRET=<generate with: openssl rand -base64 48 | tr -d '=/+' | cut -c1-48>
CRYPTO_AES_KEY=<generate with: openssl rand -hex 32>
MYSQL_ROOT_PASSWORD=<strong-password>
MYSQL_PASSWORD=<strong-password>
Generate secrets:
# CRYPTO_AES_KEY (must be exactly 64 hex chars = 32 bytes AES-256)
openssl rand -hex 32
# JWT_SECRET (>=32 chars)
openssl rand -base64 48 | tr -d '=/+' | cut -c1-48
Start services:
docker compose up -d --build
docker compose logs -f server
