Features

IP Rotation & JS Rendering

We automatically apply IP rotation and retries to every request (Free Plan included), and all our paid plans allow you to render JavaScript before extraction.

Search Country News

Free and paid plans can search the world's news with our News Search endpoint. Every request returns up to 100 news items, including metadata. Collect the URLs - then extract clean text with our Extractor endpoint.

Clean Text & Metadata

Extract clean text, HTML, image and video links, authors, title, publication date, html, and raw text. Choose only the fields you need.

API Not Required

You can extract data from up to 1,000 URLs at a time using our online visual extractor - not just the API. The visual extractor is included in all plans.

Store Your Results

Both the API and the visual extractor allow you to store your results in Jobs. Assign your target URLs a job name, then see their progress online or programmatically. Once the job is done, you can retrieve the results any time.

Translate Extracted Text

All paid accounts are able to translate to and from 55 languages. Swahili to English, Vietnamese to French, or anything you want - extract clean text and translate it with a single API call.

Koa.js features and specs

  • Lightweight
    Koa.js is designed to be a smaller, more expressive, and more robust foundation for web applications and APIs, minimizing the middleware interface.
  • Modern JavaScript
    Koa.js is built using modern JavaScript features, such as async/await, making the code more readable and easier to maintain.
  • Modularity
    Koa provides a suite of methods that make writing servers fast and enjoyable. Additionally, it doesn't come with middleware, so you can pick and choose the pieces you need, resulting in a more tailored application.
  • Error Handling
    Koa has improved error handling mechanisms compared to some other Node.js frameworks, streamlining the process of catching and managing errors.
  • Performance
    Due to its lightweight nature and the absence of bundled middleware, Koa generally has better performance metrics in terms of speed and memory consumption.

Possible disadvantages of Koa.js

  • Steeper Learning Curve
    Koa's minimalist approach and reliance on new JavaScript syntax can be challenging for beginners or those who are more accustomed to frameworks like Express.js.
  • Lack of Middleware
    Although its lack of built-in middleware promotes modularity and flexibility, it also means that developers have to spend additional time incorporating necessary middleware components.
  • Smaller Ecosystem
    Koa has a smaller ecosystem compared to more mature Node.js frameworks like Express.js. This could result in less community support and fewer third-party plugins and extensions.
  • Less Documentation
    While Koa.js has its official documentation, there are fewer tutorials, guides, and comprehensive resources available compared to some other more established frameworks.
  • Compatibility Issues
    Given that Koa.js leverages modern JavaScript features, it may not be compatible with all Node.js versions or legacy systems, necessitating careful consideration during adoption.

Extractor API Reviews

Creating an Automated Text Extraction Workflow โ€” Part 1
The 600 lbs gorilla, Diffbot, comes with a swath of solid APIs but starts at $300, which is ridiculous if youโ€™re just extracting text. Scrapinghubโ€™s News API, Extractor API, and plenty more are better priced if you want an affordable alternative; plus, Extractor API includes a visual online tool for extracting hundreds of articles at once, if you want to do things via UI.

We know you can use ChatGPT API to do the same task, but we've found that to be costly and time-consuming for the text extraction/scraping portion. We've built a cost-effective and quick tool, Extractor API, for that use case. Would love to see what others are using outside of just relying on ChatGPT for text extraction.
