Quick Start

Python — LLM Gateway (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="https://apim-ai-apis.azure-api.net/v1",
    api_key="YOUR_KEY"
)

response = client.chat.completions.create(
    model="claude-sonnet",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

Python — Pronunciation Assessment

import requests, base64

audio_b64 = base64.b64encode(open("audio.wav", "rb").read()).decode()
r = requests.post(
    "https://apim-ai-apis.azure-api.net/v1/pronunciation/assess/base64",
    headers={"Ocp-Apim-Subscription-Key": "YOUR_KEY"},
    json={"audio": audio_b64, "text": "Hello world", "format": "wav"}
)
print(r.json()["overallScore"])  # 0-100

Python — NLP Pipeline

import requests

headers = {"Ocp-Apim-Subscription-Key": "YOUR_KEY"}
base = "https://apim-ai-apis.azure-api.net/v1/nlp"

# Sentiment
r = requests.post(f"{base}/sentiment", headers=headers, json={"text": "I love this!"})
print(r.json())  # {"label": "positive", "score": 0.9987}

# PII detection with redaction
r = requests.post(f"{base}/pii", headers=headers, json={"text": "Email john@acme.com", "redact": True})
print(r.json()["redacted_text"])  # "Email [EMAIL]"

Node.js — LLM Gateway

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://apim-ai-apis.azure-api.net/v1",
  apiKey: "YOUR_KEY"
});

const res = await client.chat.completions.create({
  model: "claude-sonnet",
  messages: [{ role: "user", content: "Hello!" }]
});
console.log(res.choices[0].message.content);

curl — Image Background Removal

curl -X POST https://apim-ai-apis.azure-api.net/v1/image/remove-background/base64 \
  -H "Ocp-Apim-Subscription-Key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"image\": \"$(base64 -i photo.jpg)\"}"
