🚀 Quick REST API Examples (Using cURL)

While our SDKs provide beautiful wrapper functions, you can also connect directly to our Free AI REST API. Below are the essential HTTP requests:

1️⃣ Check API Status & Info

Verify that the AI gateway is online and responding.

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --header "Accept: application/json"

2️⃣ Get Available Free AI Models

Fetch the real-time list of AI models currently available on the gateway.

curl --location "https://api.skilledu.in/api/ai_gateway.php?action=models" \
  --header "Accept: application/json"

3️⃣ Simple POST Request (Minimal Prompt)

Send a direct prompt to the AI and receive a quick response.

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Accept: application/json" \
  --data '{
    "message": "Hello! How are you today?"
  }'

4️⃣ POST With Advanced LLM Options

Take full control over the AI's creativity and length by specifying the model, temperature, and max_tokens.

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Accept: application/json" \
  --data '{
    "message": "Write a 2-line poem about the deep oceans.",
    "model": "llama-3.1-8b-instant",
    "temperature": 0.6,
    "max_tokens": 200
  }'

5️⃣ POST With System/User/Assistant Roles

Give the AI a personality (system), provide the user's prompt (user), and pass previous context (assistant).

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Accept: application/json" \
  --data '{
    "system": "You are a highly concise programming assistant.",
    "user": "Explain what Large Language Models (LLMs) are briefly.",
    "assistant": "Previously, I explained LLMs succinctly as neural networks trained on vast text data."
  }'

6️⃣ POST With Complex Messages Array (Chat History)

If you are building a full chatbot, pass the entire conversation history inside the messages array for high-context awareness.

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Accept: application/json" \
  --data '{
    "messages": [
      {"role": "system", "content": "You are a helpful and concise productivity coach."},
      {"role": "assistant", "content": "I previously summarized the Pomodoro technique for you."},
      {"role": "user", "content": "Give me 3 more tips to learn complex topics faster."}
    ]
  }'

7️⃣ POST Long Prompt Example

Great for summarization, code generation, and extensive data processing.

curl --location "https://api.skilledu.in/api/ai_gateway.php" \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Accept: application/json" \
  --data '{
    "message": "Summarize the key pros and cons of static typing vs dynamic typing in exactly 5 bullet points."
  }'
