GitHub's REST API lets you access a surprising amount of data without any authentication. Here's what you can query for free.

Returns: name, bio, company, location, followers, public repos count.
List User Repos

Rate Limits
- Without token: 60 requests/hour (per IP)
- With token: 5,000 requests/hour
- Search API: 10 requests/minute (unauthenticated)
For most research tasks, 60 requests/hour is enough. If you need more, generate a personal access token (free).
Use Cases

I use GitHub API as one of 9 data sources in my market research tool — it shows the technology landscape for any industry.
