1,730 free APIs in one list
The most starred list on GitHub is a directory of free APIs. No install, no signup, just a table you bookmark once.
public-apis is a free, MIT-licensed GitHub repository that indexes more than 1,730 public APIs across 52 categories, from weather and finance to animals, games and machine learning. Each row records the API's name, a one-line description, whether it requires authentication, whether it supports HTTPS and whether it supports CORS, so you can rule an API in or out before writing any code. There is nothing to install: you browse the tables on GitHub, or use the searchable index, and go straight to the provider's own documentation.
What you get
- More than 1,730 APIs, grouped into 52 browsable categories
- Auth, HTTPS and CORS flagged on every row, so you can filter before you build
- A free alternative to paid data providers for prototypes and client demos
- Direct links to each provider's own docs, never a rehosted copy
- Nothing to install, and nothing to sign up for
Who this is not for
This is a directory, not a service. It does not give you keys, quotas or uptime guarantees, and the maintainers do not vet reliability. If you need a supported commercial data feed with an SLA, buy one.

Common questions
Are all of these APIs really free?
They are all free to start, but free means different things per provider. Many are free with a key and a rate limit, some are free only for non-commercial use, and a few are fully open with no registration. The list flags whether a key is needed; the provider's own page is where you confirm the limits and the licence.
Do I need to install anything?
No. It is a set of Markdown tables on GitHub. You browse it in the page and click through to the provider. That is the whole workflow.
How is this useful for automation work?
Most client automations stall on data: prices, weather, exchange rates, company lookups, holidays. This list is the fastest way to find a free source for that data and check whether it will work from n8n or a browser before you commit to building around it.
Is the list actively maintained?
Yes. It is one of the most starred repositories on GitHub with continuous community contributions. Individual entries can still go stale, so always test an endpoint before relying on it.
