Yahoo BOSS API is no longer free

The first 10k requests a day are free. Previously it was 5k.
Once you pass that threshold (it's not that low) it starts being charged according to your use.
I'd love to hear feedback on what people think about this pricing model. Please feel free to leave a comment here or email me croucher at yarrhoo dot com (remove the pirate misspelling).

The 5K limit you refer to is from the old Yahoo Search API, Yahoo Boss allowed "unlimited queries".
For all on-peak requests that would be a maximum of 10k search requests.
Off-peak it would be 30k search requests.
If you needed more results per request then the amount of free requests would be less. Spelling requests would also be counted as the same rate as off-peak. You can mix and match as much as you want.
The change would affect significantly somebody who uses API as a part of their primary function of the site [1], for example for some search mashup (like various Cuil parodies or DuckDuckGo). For these, basically each page view could be one (or more) API requests.
I understand the desire to charge for a service like this, but the way Yahoo! handled this does not encourage me to use their services (I've used BOSS extensively).

There are two examples:
* Developer A submits 7000 API requests in a given day. Each API call requests search results 1-10. Since 1000 requests of this type cost 3 units (for a total of 21 units) and each developer gets 30 units per day for free, Developer A is not charged anything.
* Developer B also submits 7000 API requests. Each API call requests results 1-100. Since 1000 requests of this type cost 10 units (for a total of 70 units) and each developer gets 30 units per day for free, Developer B will be charged for 40 units (70 - 30 = 40). The price of 40 units is $4.00 (40 x $0.10 = $4.00).
It's also worth noting that pricing is in units of 1000 requests however we will charge per request, it's just not worth quoting prices for units smaller than 1000.
