Product Matcher works on price-per-result model with $10 per 1,000 checked product pairs. The total price consists of two aspects: scraping + pairing. The scraping part depends on the complexity and scale of your data extraction. As for the pairing part, you pay for the pairs that the AI has checked, meaning both matched and unmatched pairs will be counted in.
You can find the precise price in the Matcher’s readme. If you’ve just created your Apify account, your Free plan should have enough free credits to try the Actor. But if you want to run it regularly or on any kind of scale, you will need to upgrade to a paid plan such as Starter plan with $49 in monthly usage credits. See Apify pricing for the breakdown of which of our plans might suit you best.
