Free Text Summarization API - Extract Key Points Automatically

Reading long articles takes time. You need summaries to quickly understand main points, but manually writing them is slow. Tools like TLDR.AI help, but don't integrate with workflows. What if you could summarize text programmatically via REST API and get distilled key points in seconds?

The Text Summarizer API extracts or generates summaries of any length: headlines, short summaries, full summaries. Uses extractive summarization (key sentences) and abstractive summarization (AI-generated summaries) to reduce content to its essence. Perfect for content curation, news aggregation, research synthesis, and accessibility.

Why Use This API?

Text summarization matters:

Content Curation – Summarize articles for newsletters and newsfeeds
Research – Extract key points from long academic papers
Accessibility – Provide brief summaries for users short on time
SEO – Generate meta descriptions from long content
Automation – Batch summarize thousands of documents

Quick Example - cURL

# Summarize an article
curl -X POST "https://text-summarizer-api.p.rapidapi.com/summarize" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: text-summarizer-api.p.rapidapi.com" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Your long article here...",
    "type": "short",
    "num_sentences": 3
  }'

Response:

{
  "success": true,
  "original_length": 1547,
  "summary_length": 245,
  "compression_ratio": 0.16,
  "type": "extractive",
  "summary": "Key point 1. Key point 2. Key point 3.",
  "key_points": [
    "First important finding",
    "Second important finding",
    "Third important finding"
  ]
}

Python Example

import requests

url = "https://text-summarizer-api.p.rapidapi.com/summarize"
headers = {
    "X-RapidAPI-Key": "YOUR_API_KEY",
    "X-RapidAPI-Host": "text-summarizer-api.p.rapidapi.com",
    "Content-Type": "application/json"
}

# Summarize a research paper
with open("research_paper.txt") as f:
    long_text = f.read()

# Get both short and long summaries
for summary_type in ["short", "medium", "long"]:
    payload = {
        "text": long_text,
        "type": summary_type,
        "num_sentences": 5 if summary_type == "short" else 10
    }

    response = requests.post(url, json=payload, headers=headers)
    data = response.json()

    print(f"\n{summary_type.upper()} SUMMARY ({data['summary_length']} chars):")
    print(data["summary"])

JavaScript / Node.js Example

const axios = require("axios");

const summarizeText = async (text, type = "short") => {
  const response = await axios.post(
    "https://text-summarizer-api.p.rapidapi.com/summarize",
    { text, type, num_sentences: 3 },
    {
      headers: {
        "X-RapidAPI-Key": process.env.RAPIDAPI_KEY,
        "X-RapidAPI-Host": "text-summarizer-api.p.rapidapi.com"
      }
    }
  );

  return {
    summary: response.data.summary,
    compression: `${(response.data.compression_ratio * 100).toFixed(1)}%`,
    key_points: response.data.key_points
  };
};

// Auto-generate article summaries for newsletter
const articles = await fetchArticles();
const summaries = await Promise.all(
  articles.map(a => summarizeText(a.body, "short"))
);

// Use summaries in email template
const newsletter = {
  articles: articles.map((a, i) => ({
    title: a.title,
    summary: summaries[i].summary,
    key_points: summaries[i].key_points
  }))
};
