Build Awesome Shopping Experiences

We got tired of working with heavy enterprise solutions, where everything takes forever.
So we built Clerk.io around a simple API and powerful libraries to help you get stuff done!

All the features you need, at every level of the stack

We have made Clerk.io extremely Developer Friendly at every level of the stack.


Build Anything You Want

The entire Clerk.io platform is based on a powerful API that is simple to use and gives you room to innovate.

We have built our entire App, Dashboard and Third Party Integrations on our own API after the "eat your own dog food" principle.

That way you know it works!
# Auto suggest search results for "nike sh"
curl https://api.clerk.io/v2/search/predictive\

    "query": "nike shoes",
    "hits": 438,
    "results": [1331659, 1319939],
    "product_data": [
            "id": 1331659,
            "name": "Nike Air Max 1 Ultra Moire",
            "price": 159.95
            "id": 1319939,
            "name": "Nike Air Max 1 Essential",
            "price": 95.95


Easy integration on any website

On top of our API, we provide our JavaScript library Clerk.js that makes even the most complex setups work like a breeze.

Clerk.js includes a ton of tools to take the heavy lifting out of integrating Clerk.io.
// Auto suggest search results for "nike sh"
        query: "nike sh",
        limit: 2,
        attributes: ["id", "name", "price"],

    function(response) {
        console.log("Searched for: " + response.query);
        console.log("Found " + response.hits + " hits");
        console.log("Products: ", response.product_data);


Embed using only HTML

Clerk.js comes with a powerful embed feature that allows you to embed Clerk.io results directly in to any website without a single line of code.

Just style the product presentation with HTML and Clerk.js will handle the rest.
    Auto suggest search results for "nike sh" 

    The code below will render a list of the 8 best products
    matching the query "nike sh" in the `.product-list` ul
    using only HTML markup!

    All low level rendering is handled by Clerk.js.

<!-- The product list container -->
<ul class="product-list">

  <!-- The Clerk.io Embed code -->
    class="clerk" <!-- Signal Clerk.js that this is a embed block -->

    data-api="search/predictive" <!-- The API to call -->
    data-query="nike sh" <!-- The search query -->
    data-limit="8" <!-- The number of product we want -->

    <!-- The styling applied to each product -->
    <li class="product">
      <a href="{{ url }}">
        <h2 class="name">{{ name }}</h2>
        <img class="image" src="{{ image }}" />
        <p class="price">Price: {{ money price }}</p>
