It looks like the Yahoo Boss API terms of service has recently changed to an exclusive pay as you go model and that the "Key Terms ? Query Suggestions" has been discontinued altogether according to this Boss V2 Features Matrix
Can someone confirm that the original V1 server is shut down and there is no more access to the v1 server's "Key Terms ? Query Suggestions"?
I'm asking because my key terms query is not returning data as of today. I've got a search query and API on the original Boss network that, prior to today returned related keywords for a given input string. Today, it does not answer.
Update: Thanks to Roger's answer below. It appears the Boss API has been shut down (at least in version 1).
I'm looking for an LSI search script asap. Anyone for hire to build one, let me know.
Yes, version 1 of BOSS was disabled on July 20th, replaced by version 2, which is for-pay only:
