Migrate from OpenAI to Transend AI in 5 Minutes

Switching to Transend AI takes less than 5 minutes and requires zero code changes if you're already using the OpenAI SDK.

Why Migrate?

• ✅ Access 60+ models (Anthropic, Google, xAI, Meta) with one API key
• ⚡ 25% lower latency via global edge routing
• 💰 20-40% cost savings through smart provider selection
• 🛡️ Automatic failover when providers have outages

---

Step 1: Get Your Transend API Key

1. Visit console.transendai.net/token
2. Sign up (Google/GitHub OAuth)
3. Copy your API key: sk-transend-...

Time: 60 seconds

---

Step 2: Update Your Base URL

Before (OpenAI):

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  // baseURL: "https://api.openai.com/v1"  // default
});

After (Transend AI):

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.TRANSEND_API_KEY,
  baseURL: "https://api.transendai.net/v1"  // ✨ only change
});

Time: 15 seconds

---

Step 3: (Optional) Try Other Models

Now you can access any model just by changing the model field:

// OpenAI models (same as before)
const gpt = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "Hello!" }]
});

// Anthropic Claude
const claude = await client.chat.completions.create({
  model: "claude-sonnet-4.5",  // ✨ instant access
  messages: [{ role: "user", content: "Hello!" }]
});

// Google Gemini
const gemini = await client.chat.completions.create({
  model: "gemini-2.5-pro",
  messages: [{ role: "user", content: "Hello!" }]
});

Time: 30 seconds

Environment Variables

Update your .env:

# Before
OPENAI_API_KEY=sk-...

# After
TRANSEND_API_KEY=sk-transend-...

# (Optional) Keep both for gradual migration
OPENAI_API_KEY=sk-...
TRANSEND_API_KEY=sk-transend-...

---

Python Migration

Before:

from openai import OpenAI

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

After:

from openai import OpenAI

client = OpenAI(
    api_key=os.environ["TRANSEND_API_KEY"],
    base_url="https://api.transendai.net/v1"
)

---

Vercel AI SDK Migration

Before:

import { openai } from "@ai-sdk/openai";

const model = openai("gpt-4o");

After:

import { createOpenAI } from "@ai-sdk/openai";

const transend = createOpenAI({
  apiKey: process.env.TRANSEND_API_KEY,
  baseURL: "https://api.transendai.net/v1"
});

const model = transend("claude-sonnet-4.5");

---

Monitoring & Debugging

Transend AI provides built-in observability:

1. Request Logs — See all API calls in console.transendai.net/logs
2. Latency Metrics — P50/P95/P99 per model
3. Cost Tracking — Real-time spend by model/project
4. Error Alerts — Email/Slack on 5xx errors

---

Rollback Plan

If you need to rollback, just change the baseURL back:

baseURL: "https://api.openai.com/v1"  // instant rollback

No data lock-in. No migration scripts. Just a URL change.

---

Cost Comparison

Example: 1M tokens/day on GPT-4o

For Claude/Gemini workloads, savings are even higher.

---

FAQ

Q: Do I need to change my code?

A: No. Just update baseURL and apiKey.

Q: Does streaming work?

A: Yes. SSE streaming is fully supported.

Q: What if Transend AI goes down?

A: Our SLA is 99.95% uptime. You can instantly rollback by changing the URL.
