Building Your First API in 60 Seconds

Let's Build Something

In this tutorial, we'll create a simple API that validates email addresses. By the end, you'll have a live endpoint you can call from anywhere.

Time required: Less than 60 seconds

Step 1: Sign Up (15 seconds)

Go to servep2e.com/signup and create your account. You can sign up with GitHub or Google for instant access.

Step 2: Create Your API (20 seconds)

From your dashboard, click Create New API and enter this description:

Create an API that validates an email address.
Check if the format is correct and return whether
the email appears to be valid, along with the domain.

Click Generate and wait a few seconds.

Step 3: Get Your API Key (10 seconds)

Navigate to Settings → API Keys and click Create New Key. Copy the key—you'll need it for the next step.

Step 4: Call Your API (15 seconds)

Open your terminal and run:

curl -X POST https://api.servep2e.com/v1/validate-email \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"email": "hello@example.com"}'

You'll get a response like:

{
  "email": "hello@example.com",
  "isValid": true,
  "domain": "example.com",
  "format": "valid"
}

That's It!

You just created a production-ready API in under a minute. No servers, no deployment pipelines, no configuration.

What's Happening Behind the Scenes

When you describe your API, ServeP2E:

• Parses your intent to understand what the API should do
• Generates input/output schemas based on your description
• Creates validation logic to ensure requests are well-formed
• Deploys instantly to our global edge infrastructure
• Generates documentation so you know exactly how to use it

Next Steps

Now that you've built your first API, try:

• Creating something more complex: A currency converter, weather lookup, or text summarizer
• Exploring the dashboard: See request logs, usage stats, and API documentation
• Integrating with your app: Use the API from your frontend, mobile app, or backend
