Is there any API to get all the pull requests from all the projects in the bitbucket?

Without being a participant/reviewer is there any API to get all pull requests?

There is an API endpoint to get pull requests, but it works on the repository level. So you would have to combine that with getting all the repositories associated with a project and then loop over each repository to get the pull requests.
