Public APIs: A Free List of More Than 2,000 Data Feeds Your Website Can Use
An API is a way for one piece of software to ask another website for data, like this week's weather or this year's holidays. public-apis is a free list on GitHub that collects these data feeds in one place. As of October 2026 it lists more than 2,000 of them (we counted 2,087) across 51 topics, from Weather and Calendar to Government and Food & Drink. Each row says whether you need a key (a sign-up code) to use it, and 991 rows say no key is needed.
Ways to use it this week
- A bakery or restaurant can pull the year's public holidays onto its website, so holiday hours are planned ahead instead of remembered the night before.
- A landscaper or roofer can find the US National Weather Service feed under Weather. It gives forecasts for US locations without a key.
- Any small shop can browse the Business, Shopping and Calendar topics to see what free data already exists before paying for a tool.
Try it now (no key): open https://date.nager.at/api/v3/PublicHolidays/2026/US in your browser. It returns the 2026 US public holidays, each with its date and name, as plain data. Nager.Date is one of the free entries in the Calendar topic.
Limits and rules
- The list is only a directory. Each API has its own terms, limits and uptime. Read them before you build on one.
- Some entries are for non-commercial use only. For example, the list describes Open-Meteo as a "free weather API for non-commercial use."
- The top of the page carries ads for APILayer, a company that sells paid APIs and helps curate the list. The free list starts under "Index."
- Community members and APILayer staff keep it up to date by hand, so some links go stale. Test an API before a customer depends on it.
License and credit: the list itself is under the MIT license, which lets you reuse it as long as you keep its copyright notice. That license covers the list, not the APIs in it. Each API's own terms still apply.
Golden Rock can wire a feed like this into a client's website or app, such as a holiday-hours banner or a weather note.
Who should care: any local business owner who has wished their website could show something useful that updates by itself.
