Detect if a store runs Shopify or WooCommerce, via API

The job

Lead lists for e-commerce tools, competitive research and catalog projects all start with the same question about a domain: what platform is this store on, and how big is its catalog. Answering it by hand means opening the site and reading its source.

Why an agent needs a tool for it

inspect_store answers from the store's public storefront in one call and costs 0.2 credit. An agent can run it over a list of domains to sort them by platform and size before deciding which ones to read in full.

The calls

2 tool calls.

Live production call2026-10-01

Agent calls inspect_store

{
  "name": "inspect_store",
  "arguments": {
    "store_url": "allbirds.com"
  }
}

Store Catalog answers

{
  "platform": "shopify",
  "store_url": "https://allbirds.com",
  "name": "Allbirds",
  "currency": "USD",
  "products_published": 692,
  "readable": true
}

A bare domain is enough. products_published is the count the store announces.

Live production call2026-10-01

Agent calls inspect_store

{
  "name": "inspect_store",
  "arguments": {
    "store_url": "https://porterandyork.com"
  }
}

Store Catalog answers

{
  "platform": "woocommerce",
  "store_url": "https://porterandyork.com",
  "currency": "USD",
  "products_published": 69,
  "readable": true
}

The same call on a WooCommerce store returns the same shape.

Limits worth knowing

It recognises Shopify and WooCommerce only. Any other platform, or a store that does not serve its public catalog, comes back as an error that says so.
readable means the catalog could be read at the time of the call. A store can block automated clients later.
