Step 3: Try it without writing code

If you want to see what an endpoint returns before wiring it into anything, run it in the Playground. Pick one of your API keys, fill in the parameters, and press Run. The response comes back in the browser.

The same area also holds Collections, where you can build a private knowledge graph from your own documents and ask questions grounded only in it.

Playground calls are real API calls. They deduct credits at the same rate as calls from your own code.

Step 4: Make your first request

Use the Fact Search API to search for recent news articles.

curl -X GET "https://api.factagora.com/api/v1/fact-search?q=artificial+intelligence" \
  -H "Authorization: Bearer fa_your_api_key"

import requests

response = requests.get(
    "https://api.factagora.com/api/v1/fact-search",
    params={"q": "artificial intelligence"},
    headers={"Authorization": "Bearer fa_your_api_key"}
)
print(response.json())

const response = await fetch(
  "https://api.factagora.com/api/v1/fact-search?q=artificial+intelligence",
  {
    headers: { Authorization: "Bearer fa_your_api_key" },
  }
);
const data = await response.json();
console.log(data);

Step 5: Understand the response

A successful response returns a list of news articles with metadata:

{
  "query": "artificial intelligence",
  "articles": [
    {
      "title": "OpenAI releases new model",
      "url": "https://techcrunch.com/...",
      "domain": "techcrunch.com",
      "publishedAt": "2025-03-30T12:00:00Z",
      "language": "english",
      "sourceCountry": "US",
      "snippet": "OpenAI has announced...",
      "source": "gnews"
    }
  ],
  "meta": {
    "total": 42,
    "executionTimeMs": 312,
    "source": "gnews",
    "cached": false
  }
}
