是的，Bitbucket有类似GitHub的git-blame功能，可以在一行上使用。可以使用Bitbucket的API来获取文件的blame信息。

下面是一个使用Bitbucket API获取blame信息的示例代码（使用Python和requests库）：

import requests

# Bitbucket API endpoint for getting blame information
api_url = "https://api.bitbucket.org/2.0/repositories/{username}/{repo_slug}/src/{branch}/{file_path}/annotations"

def get_blame_info(username, repo_slug, branch, file_path):
    # Make a GET request to the API endpoint
    url = api_url.format(username=username, repo_slug=repo_slug, branch=branch, file_path=file_path)
    response = requests.get(url)

    # Check if the request was successful
    if response.status_code == 200:
        # Parse the JSON response
        blame_info = response.json()

        # Print the blame information for each line
        for annotation in blame_info["values"]:
            line_number = annotation["line"]
            author = annotation["user"]["display_name"]
            commit = annotation["commit"]["hash"]
            print(f"Line {line_number}: Author - {author}, Commit - {commit}")
    else:
        print("Failed to get blame information")

# Usage example
get_blame_info("username", "repo_slug", "branch", "file_path")

请使用实际的Bitbucket用户名、仓库slug、分支和文件路径替换示例代码中的占位符。这将打印出文件的每一行的作者和提交信息。

通过这种方式，您可以在Bitbucket上实现类似git-blame的功能。
