No, there aren’t.
Due to the nature of our software implementation, we can’t hand out unlimited or lifetime licenses—because that inexhaustible licensing value would quickly outweigh our costs via third-party services, like the dictionary API.
To depict this, each dictionary API request to our servers costs us about $0.004.
So, say that you manage 2000 blogs, each of which uses our dictionary-services only once a day (that’s 6000 requests): that’ll cost us about $24 per day, or about $8760 per year. It’d be absurd and unreasonable for us to account and quantify such huge charges, and forward those to you.
Nevertheless, we do have generous pricing options available via our bulk-licensing subscription options, like the Business and Agency subscriptions.
Although we hand you more than $2400 worth of API credit (600,000 requests) per year for Agency (which costs you $324/year), we evaluated that the unrestricted character of that subscription brings more value (and therefore, to be transparent, more sales) than it would cost us. Because, eventually, the users that use the API less should level out the total usage and costs.
