AGPipeline* pipeline = [AGPipeline pipelineWithBaseURL:BASE_SOCCER_APP_URL];

id<AGPipe> leagues = [pipeline pipe:^(id<AGPipeConfig> config) {
    [config setName:@"leagues"];

    [config setNestedPipes:[@"teams", @"players"];  // an array of nested resources for this pipe
}];

A new "pipe" method is added in the pipeline with params the Parent ID's of this nested resource. Once returned you have a fill Pipe to invoke operations on.
