Use this guide when your app already calls OpenAI from TypeScript, JavaScript, or Python. Change only the API key, base URL, and model id.

​
TypeScript

npm install openai

import OpenAI from "openai";

const client = new OpenAI({
	apiKey: process.env.AI_STATS_API_KEY,
	baseURL: "https://api.phaseo.app/v1",
});

const response = await client.responses.create({
	model: "openai/gpt-5-nano",
	input: "Write one sentence about reliable model routing.",
});

console.log(response.output_text);

​
Python

pip install openai

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["AI_STATS_API_KEY"],
    base_url="https://api.phaseo.app/v1",
)

response = client.responses.create(
    model="openai/gpt-5-nano",
    input="Write one sentence about reliable model routing.",
)

print(response.output_text)

​
Chat Completions

Older libraries may still call Chat Completions: 
const completion = await client.chat.completions.create({
	model: "openai/gpt-5-nano",
	messages: [{ role: "user", content: "Reply with only: ok" }],
});

​
Notes

  • Use AI Stats model ids, including provider prefixes such as openai/, anthropic/, or google/.
  • Server tools use AI Stats tool names such as ai-stats:web_search.
  • For Anthropic-native clients, use the Anthropic SDK guide instead.
