Extraction Endpoint

POST

https://url-to-markdown2.p.rapidapi.com/v1/extract

Request Body Details

Parameter (JSON)	Type	Required	Description
`url`	String \| Array	Yes	The absolute target URL(s) to scrape. Pass an array for concurrent batching (max 5).
`selector`	String	No	A CSS selector to precision-target specific DOM content (e.g. `.article-body`).
`metadata`	Boolean	No	If true, includes extra fields like `title` and `excerpt` in the response. Default: false.

Code Example: Single URL (cURL)

curl --request POST \
  --url https://url-to-markdown2.p.rapidapi.com/v1/extract \
  --header 'Content-Type: application/json' \
  --header 'x-rapidapi-host: url-to-markdown2.p.rapidapi.com' \
  --header 'x-rapidapi-key: YOUR_KEY' \
  --data '{"url": "https://sinyx.me"}'

Code Example: Batch Processing (cURL)

Extract up to 5 URLs in parallel. If one fails, the others still succeed.

curl --request POST \
  --url https://url-to-markdown2.p.rapidapi.com/v1/extract \
  --header 'Content-Type: application/json' \
  --header 'x-rapidapi-host: url-to-markdown2.p.rapidapi.com' \
  --header 'x-rapidapi-key: YOUR_KEY' \
  --data '{"url": ["https://apple.com", "https://github.com"], "metadata": true}'

Code Example: Batch Processing (Python)

import requests

url = "https://url-to-markdown2.p.rapidapi.com/v1/extract"
payload = { 
    "url": [
        "https://apple.com",
        "https://github.com"
    ],
    "metadata": True
}
headers = {
    "x-rapidapi-key": "YOUR_KEY",
    "x-rapidapi-host": "url-to-markdown2.p.rapidapi.com",
    "Content-Type": "application/json"
}

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