Many SGD page URLs can be prepended with /webservice/ to get a JSON representation of the object.
For example, see https://www.yeastgenome.org/webservice/locus/S000003131 as an example of a locus object.
example https://www.yeastgenome.org/webservice/locus/S000003131
SGDID can also be a standard gene name or ORF name

The search API lists very basic information (such name, URL, id, and category) for many entities in SGD. Without any paremeters, it will match anything (but only show first 25 results).
https://www.yeastgenome.org/webservice/get_search_results
That query can be altered with the following query params
qquery to match in results, can be any string, such askinasecategoryone oflocus,reference,biological_process,cellular_component,molecular_function,chemical,phenotype,observable,strain,resource,colleague,reserved_namelimitnumber of results to return. If left blank, will return 25 resultsoffsetwhere to start retrieving results. If set to 10, will get results 10-35 (wherelimitis 25)
The following search will get 100 Molecular Functions that match the query "kinase"
