Right now I don't see a way of programmatically accessing Pipelines. It wold be very useful if pipeline operations were exposed in REST API. These operations could include:

• GET a list of pipeline runs (along with results, etc)
• POST a request to run pipeline for specific commit or branch
• cancel (DELETE) a running pipeline

It would enable such scenarios as: invoking pipeline from command line, pipeline status monitoring, etc. An example of a similar API is AppVeyor's builds API
