427,000 Stars and Still Needs Your Pull Request

Why the internet's favorite free-API list is quietly asking for help There is a GitHub repository with more stars than most cities have residents, and its maintainers are still manually reviewing whether a weather API still works or whether a link has gone dead. That gap — enormous popularity, tiny team — is exactly why this is a good place to show up. Setting public-apis/public-apis started as a simple idea: collect every publicly available, free API into one organized list so developers don't have to hunt across a dozen blog posts. Today it holds hundreds of categorized entries — everything from cat facts and NASA image data to payment processors and machine translation services. With 427,000 GitHub stars it is, by most measures, one of the most-starred repositories on the internet. The core team is small. The project is structured around community contributions: someone discovers a broken link, someone else knows a new API worth adding, a third person notices a category is mislabeled. The maintainers review pull requests (proposed changes submitted by anyone in the community) and merge the good ones. That loop works — but only when contributors actually show up. The Story Here is what the contribution workflow looks like in practice. Say you are building a side project and you discover that a free geolocation API (a service that tells you what country an IP address belongs to) is not listed. You fork the repo (make your own copy on GitHub), open the README.md file, find the "Geocoding" section, and add one line in the correct format: API name, a short description, whether it requires authentication, whether it supports HTTPS, and whether it allows CORS (cross-origin requests, which matters for browser-based apps). You open a pull request explaining what you added and why it belongs. A maintainer reviews it. If the entry is accurate and properly formatted, it gets merged. That is a real, completable contribution that takes about 20 minutes if you already know the API. No complex codebase to understand. No testing framework to configure. Just a text file and a clear format to follow. Other entry points exist too. Some listed APIs have gone offline since they were added — links that return 404 errors ("not found" responses) instead of real documentation. Catching one of those and opening a removal PR is equally valid work. For anyone with Python knowledge, there is also an automated validation script in the repository that checks entries for formatting consistency; contributing to that layer requires more familiarity with the codebase but is well within reach for a junior developer who wants a slightly more technical challenge. The project does not currently maintain a tightly curated list of "good first issues" (GitHub's label for beginner-friendly tasks) in the way that heavily staffed open-source projects do. That is honest information worth knowing before you arrive. You will need to read the contributing guidelines in the repository and exercise a little judgment about where to start. The Insight The contribution barrier here is unusually low — but that cuts both ways. Because adding an entry is simple, the quality bar for what you add matters more than your technical credentials. A well-researched, clearly described API entry from someone who has actually used the service is more useful than a hastily added link from someone chasing commit count. The maintainers are not looking for volume; they are looking for accuracy. For a junior developer building a portfolio, this is a realistic place to get a real merged pull request into a project that developers around the world actually use daily. That is not nothing. For a developer who has contributed to closed codebases for years and wants to understand open-source culture, this repository is a low-stakes environment to practice the pull request workflow — the etiquette, the back-and-forth of review, the patience of waiting. The solidarity angle is simple: a project this widely used deserves more than a skeleton crew keeping it alive. The people who benefit from it — and that is a significant portion of the developer internet — are the natural candidates to maintain it. If this feels like the right size of first step, start with the contributing guidelines in the repo, pick one API you know and trust, and write one clean entry. The maintainers will take it from there.
