The OpenAI SDK base_url / baseURL normally includes /v1.

python -m pip install openai

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["CODEX_RELAY_API_KEY"],
    base_url="https://codexapi.asia/v1",
)

response = client.responses.create(
    model="MODEL_ID",
    input="Explain what an API gateway does in one sentence.",
)

print(response.output_text)

Node.js

npm install openai

import OpenAI from 'openai'

const client = new OpenAI({
  apiKey: process.env.CODEX_RELAY_API_KEY,
  baseURL: 'https://codexapi.asia/v1',
})

const response = await client.responses.create({
  model: 'MODEL_ID',
  input: 'Reply with a short greeting.',
})

console.log(response.output_text)

Chat Completions

curl https://codexapi.asia/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MODEL_ID",
    "messages": [{"role": "user", "content": "Hello"}],
    "stream": true
  }'

Environment variable

export CODEX_RELAY_API_KEY="YOUR_API_KEY"

Do not hard-code keys in production. Use your CI/CD secret store and assign separate keys to separate environments.
