Yahoo Makes money now from Yahoo search BOSS developer network:

BOSS is currently offered to developers free of charge. In the near future (likely late Q2 2009), we plan to implement a fee structure for API use above a set threshold.

BOSS will continue to offer free use of the API below a set daily threshold - up to 10,000 search queries per day depending on the type of API call. In addition, we plan to implement a service level agreement (SLA) in parallel with fees. We will announce firm timing and further details when we get closer to launch.

When we implement fees, we also plan to offer developers the ability to make non-time sensitive API requests at a significantly reduced price. This "off-peak" option can be used for research and analysis efforts to support building search experiences and would allow developers to request queries to be fulfilled by BOSS when capacity permits.

We currently plan to implement a fee system with the following structure:

· Fees will be determined based on the number and type of API requests made per day

· We are no longer restricting developers from monetizing their products using third-party platforms

· Fees will be determined using a unit system

· Units for Web, News, and Image BOSS API calls will be incurred based on the last result requested. For example, an API call requesting results 91-100 is the same cost as one requesting results 1-100

· Developers may request up to 1000 results in a single API call

· Units will cost $.10

· Developers will receive 30 units per day for free of charge
