10 Free APIs Every AI Developer Should Know

These APIs can help you build smarter AI tools without spending a fortune

You don’t have to build everything from scratch when making AI apps. There are APIs that allow you to search the web, pull content from websites, run AI models, and even improve the answers your AI gives.

I found 10 useful APIs that developers can start using for free. Some offer monthly credits, while others provide limited free access or don’t require an API key at all.

Here is what each one does and how you can use it in your own projects.

1. Tavily API

AI models don’t always have access to the latest information. Tavily helps solve this problem by allowing your application to search the web and retrieve relevant results.

For example, you could build an AI research assistant that searches for recent developments in artificial intelligence and summarizes what it finds.

Tavily offers a free plan with 1,000 API credits per month.

Here is a simple Python example:

from tavily import TavilyClient

client = TavilyClient(api_key="YOUR_API_KEY")
results = client.search(
    query="Latest AI developments"
)
for result in results["results"]…
