MegaMWS gathers Amazon Product data from multiple MWS (Marketplace Web Service) calls and returns it in a single, easy-to-use result.
Designed for anyone that needs access to salesranks, meta-data, offers, buy-box prices, or category data. Especially useful if you need more data than your MWS account will allow due to Amazon's strict quota system.
To use the system, you must authorize the MegaMWS system in your Amazon Seller Central account. You'll take information from there and input it into MegaMWS and that will allow you to use the system.
Plans start at $10. Check out the pricing page for more details.
The system is currently in alpha and should be more widely available soon.
Buyback websites, prospectors, and others need Amazon data en bulk. Trying to get it directly from Amazon is nearly impossible, and MegaMWS makes it easy.
You can register for your account here. Once you've authorized MegaMWS and have input the necessary credential details, you'll automatically receive 100,000 free credits!
