A few different things here. 1: Unlikely, most often this leads to complicated pricing structures, and would you really be willing to take less from a store using it to sell... Candy vs a Store using it to sell say, Ovens. 2: It's likely better based on usage. 3: That is likely integration cost + contracted usage / time-frame. 4: Figure out what your infrastructure can support. Get estimated traffic from the types of sites you want to be a part of. Is the traffic on every page, or just the 'thank you' page. Do comparisons. Chances are you'll need adjustments (either on the API itself, or the inbound traffic) to avoid performance issues. Multiply that by the number of customers you expect to get a rough approximation of the total calls and the max ballpark of each customer. Recommend coming in somewhere below the Max throughput as the targeted baseline cap (figure out if cap is daily, weekly, monthly, quarterly, etc, and how those differences affect your inbound traffic). Some things to think about... Does the API have security on it that needs to be configured? Do you have a customer facing Dashboard that proves to the customer that your product works via API analytics (how much traffic they've used, etc)? Do you have a customer facing Dashboard that allows the client to make any changes to the configuration of the data return, or is that all done in the URL signature. Can the requested Signature and the Dashboard have different configurations, if so, which wins? Do you have a Analytics integration package that proves to the customer that your product works? Do you have an idea of how your product would work in a A/B test scenario? Do you intend to prove value real time, and if so - does that mean your API needs to account for 'hold out' scenarios to establish a comparison baseline? Do you have your API documented for Developers, including sample requests and same responses to build their integration around?
