GitHub Stargazer Data Extractor

Extract accurate profile data from GitHub stargazers (users that star a repository).

Given a repo URL, the actor returns a list of records like this one:

{
"login":"username",
"email":"user@example.com",
"name":"Full Name",
"location":"San Francisco, CA",
"company":"Acme Inc",
"blog":"https://example.com",
"twitter":"handle",
"followers":120,
"public_repos":34,
"profile_url":"https://github.com/username",
"email_found":true
}

Features

• High Accuracy: Only returns emails from actual stargazers (not random contributors)
• Fast Processing: Concurrent extraction with intelligent rate limiting
• Token Rotation: Support for multiple GitHub tokens for higher throughput
• Proven Results: 92.8% average hit rate across major repositories

Input

Using this actor requires a Github account, as you need to provide at least one Personal Access Token with 'public_repo_access'.

This results in faster, more reliable results.

Input fields:

How to get your Github Personal Access Token

1. Go to GitHub Settings → Tokens
2. Click "Generate new token (classic)"
3. Select public_repo scope
4. Copy the token (starts with ghp_)
5. Add to the tokens array

Output

Each stargazer record may include:

{
"login":"username",
"email":"user@example.com",
"name":"Full Name",
"location":"San Francisco, CA",
"company":"Acme Inc",
"blog":"https://example.com",
"twitter":"handle",
"followers":120,
"public_repos":34,
"profile_url":"https://github.com/username",
"email_found":true
}

• email_found: true if email was found, false otherwise

Some fields can be undefined because some users keep them private.
