Quick Start
Make your first API request in under 5 minutes. No provider accounts, no additional configuration.
Prerequisites
- A Proxyify account — sign in with Google
- An API key — create one from Dashboard → Keys
- Python 3.8+ or Node.js 18+ or curl
Install SDK
Proxyify uses the standard OpenAI SDK. No custom package needed.
bash
pip install openai
bash (Node)
npm install openai
First request
The only change from a standard OpenAI setup is the base_url. Everything else — method names, parameters, response shapes — stays identical.
Python
from openai import OpenAI
client = OpenAI(
api_key="prx-xxxxxxxxxxxxxxxx", # your Proxyify key
base_url="https://proxyify.dev/v1",
)
response = client.chat.completions.create(
model="openai/gpt-4o-mini",
messages=[{"role": "user", "content": "Explain REST APIs in one sentence."}],
)
print(response.choices[0].message.content)
JavaScript / Node
import OpenAI from "openai";
const client = new OpenAI({
apiKey: "prx-xxxxxxxxxxxxxxxx",
baseURL: "https://proxyify.dev/v1",
});
const res = await client.chat.completions.create({
model: "openai/gpt-4o-mini",
messages: [{ role: "user", content: "Explain REST APIs in one sentence." }],
});
console.log(res.choices[0].message.content);
curl
curl https://proxyify.dev/v1/chat/completions \
-H "Authorization: Bearer prx-xxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"model": "openai/gpt-4o-mini",
"messages": [{"role": "user", "content": "Explain REST APIs in one sentence."}]
}'
Every response includes a _balancer field with credits_used, cost_usd, and latency_ms. You can see all requests in Dashboard → Logs.
