The workflow
- For Amazon, run Amazon products with up to ten ASINs or product URLs: price, list price, deal and Prime flags, availability and seller.
- For a Shopify store, run Shopify products with the store URL, up to five stores per call: every product with its price range, sale flag, stock and variants.
- For the wider market, run Google shopping with a product query and a country: title, merchant, price and rating per offer.
- Read Amazon history (price, list_price) and Shopify history (price_from, price_to, in_stock) for free to chart what past captures saw.
- Run it on a schedule from your own job and alert when a price or stock flag changes.
Who uses it
Marketplace sellers
Watch the Amazon listings you compete with for price, deal flags and best-sellers rank, and reprice from data.
Pricing analysts
Compare one product across merchants with Google Shopping, then follow the ones that matter on their own stores.
Operations used
List prices per record. A call can carry a minimum, so quote first: the quote is free, and a record that does not come back is not charged.
| Step | Operation | What comes back | Price |
|---|---|---|---|
| 1 | Amazon products | Price, list price, deal and Prime flags, availability, seller | $0.0014 per record |
| 2 | Shopify products | Every product with price range, sale flag, stock, variants | $0.0009 per record |
| 3 | Google shopping | Offers with title, merchant, price, rating | $0.0027 per record |
The operations in this workflow
Questions people ask.
Does history cost anything?
No. History reads only what earlier captures already stored, at no charge. It does not fetch new prices; run the products call for that.
Which Shopify stores work?
Any Shopify-powered storefront, by store URL, up to five per call.
Can I track an Amazon price in another country?
Yes. Set marketplace to the site's domain suffix, such as co.uk, de or in. A product URL carries its own site.

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.
