gpt2api-Anthropic-gateway — Claude Code skill: Claude Code Image
This skill walks your agent through deploying a self-hosted Anthropic-compatible gateway over chatgpt.com and wiring up an account pool.
npx skills add reason-machines/trending-skills --skill gpt2api-openai-gateway -a claude-codeWhat gpt2api-openai-gateway does
The skill covers gpt2api, a self-hosted gateway that exposes /v1/images/generations, /v1/images/edits and /v1/chat/completions in Anthropic format. It ships the Docker Compose steps, the configs/config.yaml layout, account import and API key creation through the admin dashboard.
Three secrets go into .env before anything starts: JWT_SECRET, CRYPTO_AES_KEY and the MySQL passwords. The AES key has to be exactly 64 hex characters or the service will not boot. Claude accounts are imported in bulk, either as JSON sessions with access_token and refresh_token or as plain AT/RT/ST lines, and proxies are registered separately.
Once running, the gateway drops into the official SDKs — swap base_url for your instance and the rest of the code stays put. A scheduler enforces a minimum interval between hits on the same account and backs off on a 429. Skip the proxy setup and the pool degrades fast.
What it helps with
- stand up an Anthropic-compatible gateway to chatgpt.com on your own server
- build a Claude account pool with rotation and rate limits
- generate images in batches through
/v1/images/generations - point the Python or Node.js SDK at your gateway without rewriting code
- issue API keys with quotas and a model whitelist
Example prompts for the agent
- deploy gpt2api with Docker Compose and generate the .env secrets
- add a new Claude account to the pool with its access_token and refresh_token
- show me how to call Claude-image-2 from the Python SDK through my gateway
