Rest API to get pipeline children

:hugs: Currently, API call to get Pipelines is https://domain/api/v4/projects/:id/pipelines
It would result in an array of JSON objects. Each Object got commitId that needs to be passed to the following API to get pipeline children details:
This is good for just one or two API calls and not suitable for bulk of pipelines. Is there a way to circumvent this issue? Is there a way to get all Pipelines children without passing commitId? That means https:domain/api/v4/projects/projects/:id/pipelines/??
Please help.
