Public API

What It Is and Who It's For

Public APIs is a collaborative, community-curated directory listing over 1400 public APIs across diverse categories including animals, books, cryptocurrencies, development, music, weather, and more. The platform is designed for API developers and companies who want to make their tools discoverable to the global developer community. It serves as a central hub where developers can find ready-to-use APIs to integrate into their applications, making it an ideal submission destination for startups offering API-based products or services.

SEO Value and Link Profile

With a Domain Rating of 34.0, Public APIs offers a moderate-authority backlink that can contribute to your SEO profile. The directory attracts developers actively searching for API solutions, meaning traffic from this source tends to be highly targeted and relevant—developers looking to integrate tools are qualified potential customers. Submissions appear alongside other legitimate API offerings, providing contextual relevance that search engines value. The platform's emphasis on genuine developer benefit (rather than pure marketing) means links carry more credibility within the developer community and search algorithms.

Getting Listed and Best Practices

To successfully submit your API, ensure it offers genuine value to developers rather than positioning the submission purely as a marketing channel. Provide clear documentation, consider offering a free tier or free trial to lower barriers to entry, and highlight specific use cases that solve real developer problems. Include accurate categorization, detailed descriptions of your API's functionality, and links to comprehensive documentation. The more useful your API is to the developer community, the more likely it is to gain visibility, backlinks from other sources, and organic traffic—creating a virtuous cycle for both SEO and user acquisition.
