##
## source template: template/api.yaml
## note:
##     Configure a credential of type API Keys for this endpoint, i.e., $${name}.endpoints.$${project_id}.cloud.goog
##     and pass key=$${credential} with requests for query, then it should work.
##          If a request without access key (credential) is sent, you will get the following forbidden message:
## {
##  "code": 3,
##  "message": "API key not valid. Please pass a valid API key.",
##  "details": [
##   {
##    "@type": "type.googleapis.com/google.rpc.DebugInfo",
##    "stackEntries": [],
##    "detail": "service_control"
##   }
##  ]
## }
##          If a request with wrong access key, for example, you forgot to configure API restrictions to allow traffic for this API,
##     or, you give a credential outside of this endpoint service, you will get the following questioning message:
## {
