<SYSTEM_TASK:>
Given the following text description, write Python code to implement the functionality described below step by step
<END_TASK>
<USER_TASK:>
Description:
 Default Behavior of BTE
Step1:  As you can see above, by default, BTE will query all APIs integrated.
Remove a specific API or a list of APIs from BTE
Step2:  The Registry class stores all APIs used in BTE.
To remove one or more API from the registry, use the method below
Step3:  check the current api list
Step4:  So now, the "biolink" and "dgidb" are removed from the registry
We then pass the registry as a parameter to the FindConnection Class.
Step5:  If you look through the query log above, the API "biolink" and "dgidb" are no longer querid.
Specify a list of APIs to include

Python Code:
from biothings_explorer.user_query_dispatcher import FindConnection
from biothings_explorer.hint import Hint
ht = Hint()
# find all potential representations of CML
cml_hint = ht.query("MONDO:0011996")
# select the correct representation of CML
cml = cml_hint['Disease'][0]
cml
# find all potential representations of imatinib
imatinib_hint = ht.query("imatinib")
# select the correct representation of imatinib
imatinib = imatinib_hint['ChemicalSubstance'][0]
imatinib
fc = FindConnection(input_obj=cml, output_obj=imatinib, intermediate_nodes='Gene')
fc.connect(verbose=True)
Explanation: Default Behavior of BTE

from biothings_explorer.registry import Registry
reg = Registry()
reg.show_all_apis()
Explanation: As you can see above, by default, BTE will query all APIs integrated.
Remove a specific API or a list of APIs from BTE
End of explanation
reg.remove_apis(['biolink', 'dgidb'])
Explanation: The Registry class stores all APIs used in BTE.
To remove one or more API from the registry, use the method below:
End of explanation
reg.show_all_apis()
Explanation: check the current api list
End of explanation
fc = FindConnection(input_obj=cml, output_obj=imatinib, intermediate_nodes='Gene', registry=reg)
fc.connect(verbose=True)
Explanation: So now, the "biolink" and "dgidb" are removed from the registry
We then pass the registry as a parameter to the FindConnection Class.
End of explanation
reg.refine_api_list(["semmed_chemical", "semmed_disease"])
reg.show_all_apis()
fc = FindConnection(input_obj=cml, output_obj=imatinib, intermediate_nodes='Gene', registry=reg)
fc.connect(verbose=True)
