The ideas
A price change alert
For brands and buyers. It charts each product's price range from the stored series, which is free, and flags changes. Uses products and history.
A sale tracker
For deal sites and shoppers. It reads the sale flag across a set of stores and lists what is on sale today. Uses products.
A stock-out monitor
For brands that sell through independent retailers. It checks stock on their products in each retailer's store. Uses products and history.
A product feed for a comparison site
For small comparison and gift sites. It gathers products from several stores into one list with price, stock and variants. Uses products.
A reseller price check
For brands. It reads the stores that carry their products and compares the prices they show. Uses products.
A niche market map
For founders and analysts. It compares catalogue size, price ranges and variant counts across stores in one niche. Uses products.
A pricing research dataset
For analysts. It reads stores on a schedule and keeps the stored price and stock series for later study. Uses products and history.
A gift finder agent
For shoppers. An agent reads a short list of independent stores and suggests products in a price range that are in stock. Uses products.
A store qualifier for app and agency sellers
For agencies and app makers selling to stores. It reads a store's catalogue size and variant counts to see whether it fits. Uses products.

How to start
- Sign up. An agent registers itself with one POST and starts with $0.10 of free credit; a person can sign up on the site instead.
- Quote the first call for free: send the products request with "estimateOnly": true and read the price before anything is spent.
- Run the same call with "maxUsd" set as a ceiling, and keep the rows it returns.
- Schedule it: repeat the call daily or weekly, and read the stored series with history, which is free.
Operations used
Questions people ask.
What do I pass in?
Up to five storefronts per call, by store URL. Each returns its products with price range, sale flag, stock, variants and options.
Do I need a Shopify account to build these?
No. The API reads public data and never asks for your login, password or cookie.
What does a run cost?
Shopify records are priced from $0.0009 per record. A call can carry a minimum, so send it first with "estimateOnly": true. The quote is free and is the most the call can cost.
Can an AI agent build and run these on its own?
Yes. It signs itself up with one call and gets $0.10 free, quotes each call before it spends, and pays from a prepaid balance. "maxUsd" caps every call, and only a person can add money.
Try it in a minute. $0.10 free.
The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.
Why people pick API for Agents
- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.
