Introduction

Web scraping and data extraction are crucial for transforming vast online datasets into formats suitable for large language models (LLMs).

Kadoa as an API-first company, ensures seamless integration by making core features accessible through robust API endpoints. This guide walks you through leveraging Kadoa’s web crawling capabilities via its /crawl API endpoint. You’ll learn how to:

  • Initiate a crawling session
  • Check crawling session status
  • List crawled pages
  • Access Crawled Page Content

​
Authentication

​
Get Your API Key

To authenticate, retrieve your personal Kadoa API key from your Kadoa Dashboard.

​
API Request Headers

Include your API key in the headers of each API request:

{ 
    "x-api-key": "<Kadoa API Key>" 
}

​
How It Works

​
Initiate a crawling session

To initiate a web crawl, send a POST request to the /crawl endpoint with the desired configuration.

POST https://api.kadoa.com/v4/crawl

Body parameters:

  • url: String, required. The root URL to target for the operation (e.g., www.example.org).
  • pathsFilterIn: Array of strings, optional. Specifies URL path patterns to include in the operation (e.g., ["/shop"]).
  • pathsFilterOut: Array of strings, optional. Specifies URL path patterns to exclude from the operation (e.g., ["/about"]).
  • timeout: Positive integer, optional. Represents the timeout duration in seconds.
  • maxDepth: Positive integer, optional. Specifies the maximum depth of crawling (e.g., 10).
  • maxPages: Positive integer, optional. Specifies the maximum number of pages to crawl (e.g., 1000).
  • strictDomain: Boolean, optional. Enforces crawling only within the same domain (e.g., true for staying on www.acme.org and not traversing to docs.acme.org).
  • proxyCountry: String, optional. Represents the proxy country code (e.g., "US", "DE", "FR", "IT", "BR", …).

Configuration Notes:

Use pathsFilterIn and pathsFilterOut to include or exclude specific paths. Adjust timeout, maxDepth, and maxPages to refine the crawling process.

​
Check Crawl status

Monitor the progress of your crawling session using the /crawl/status/<sessionId> endpoint.

GET https://api.kadoa.com/v4/crawl/<sessionId>/status

Sample Response:

{
    "payload": {
        "finished": false,
        "crawledPages": 20
    },
    "sessionId": "<sessionId>",
    "error": null
}

​
List Crawled Pages

Access the crawled pages using the /crawl/<sessionId>/pages endpoint with pagination.

GET https://api.kadoa.com/v4/crawl/<sessionId>/pages?currentPage=<page_number>&pageSize=<page_size>

Query parameters:

  • currentPage: Positive integer, starting from 0.
  • pageSize: Positive integer, starting from 1.

Sample Response:

{
    "payload": [
        { "id": "<pageId>", "url": "https://example.com", "status": "DONE" },
        { "id": "<pageId>", "url": "https://example.com/about", "status": "CRAWLING" }
    ],
    "pagination": {
        "currentPage": 1,
        "pageSize": 25,
        "totalRecords": 132,
        "totalPages": 5
    },
    "sessionId": "<sessionId>",
    "error": null
}

​
Access Crawled Page Content

Use the /crawl/<sessionId>/pages/<pageId> endpoint to retrieve the content of individual crawled pages in your preferred format. The API can deliver the page payload directly in an LLM-ready format, such as markdown.

GET https://api.kadoa.com/v4/crawl/<sessionId>/pages/<pageId>?format={html|md}

Supported Formats:

  • html: Full HTML structure
  • md: Markdown format

Sample response (Markdown):

{
    "payload": "# Sample Markdown\n\n## Heading 2\n\nThis is a **bold** text and this is *italic*.\n\n",
    "pageId": "<pageId>",
    "pageFormat": "md",
    "error": null
}

Sample response (HTML):

{
    "payload": "<!DOCTYPE html>\n<html>\n<head>\n<title>Sample HTML</title></head><body>...</body>\n</html>",
    "pageId": "<pageId>",
    "pageFormat": "html",
    "error": null
}
