Configure Codex CLI with Earbowe API

Codex CLI is OpenAI’s terminal-based coding agent. You can point it at any OpenAI-compatible endpoint — including Earbowe.

Setup

1. Set environment variables

export OPENAI_BASE_URL="https://api.earbowe.com/v1"
export OPENAI_API_KEY="sk-YOUR-KEY"

For China-direct access:

export OPENAI_BASE_URL="https://api.3861343.xyz/v1"
export OPENAI_API_KEY="sk-YOUR-KEY"

2. Verify the connection

curl -s "$OPENAI_BASE_URL/models" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  | python3 -c "import sys,json; [print(m['id']) for m in json.load(sys.stdin)['data'][:5]]"

You should see a list of available model IDs.

3. Start Codex

codex

Codex will use the environment variables automatically. No config file needed.

Model selection

Codex works best with strong models. On Earbowe, try:

• gpt-5.1-codex — Codex-optimized
• gpt-5.5 — latest GPT
• claude-sonnet-4-20250514 — Anthropic’s coding model
• deepseek-v4-pro — cost-effective alternative

Check /v1/models for the current list.
