How to Scrape Reddit Comments Tree with cURL

Reddit Comments Tree contains valuable data — comment text, author, score, depth, and more. Scraping this data directly means dealing with anti-bot detection, CAPTCHAs, IP rotation, and constantly breaking selectors. The Scavio API handles all of that and returns clean, structured JSON from a single POST request.

This tutorial shows you how to scrape Reddit Comments Tree using cURL and the Scavio API. By the end, you will have a working cURL script that fetches real-time Reddit Comments Tree data and parses the results.

Prerequisites

• A terminal with cURL installed (pre-installed on macOS, Linux, and Windows 10+)
• A Scavio API key (free tier includes 500 credits/month — no credit card required)

Step 1: Install Dependencies

curl is built into cURL, so there is nothing to install.

Step 2: Make Your First Reddit Comments Tree Search

Send a POST request to the Scavio Reddit Comments Tree API endpoint with your query. The API returns structured JSON with comment text, author, score, and more.

curl -X POST "https://api.scavio.dev/api/v1/search" \
  -H "x-api-key: your_scavio_api_key" \
  -H "Content-Type: application/json" \
  -d '{"query":"r/ChatGPT best prompt for summarizing long articles"}'

Step 3: Example Response

The API returns structured JSON. Here is an example response for a Reddit Comments Tree search:

{
  "search_metadata": { "status": "success" },
  "post": {
    "title": "Best prompt for summarizing long articles?",
    "subreddit": "ChatGPT",
    "score": 428
  },
  "comments": [
    {
      "id": "k8m2x1a",
      "parent_id": null,
      "depth": 0,
      "author": "u/prompt_eng",
      "score": 312,
      "text": "I use a 3-pass prompt: outline, claims, then TL;DR with citations."
    },
    {
      "id": "k8m3p9b",
      "parent_id": "k8m2x1a",
      "depth": 1,
      "author": "u/dev_curious",
      "score": 94,
      "text": "Does this handle articles over 50k tokens?"
    }
  ]
}

Every field is structured and typed — no HTML parsing, no CSS selectors, no regex extraction. Your cURL code can access any field directly.

Step 4: Full Working Example

Here is a complete, runnable cURL script that searches Reddit Comments Tree and prints the results:

#!/bin/bash
# Scrape Reddit Comments Tree search results using Scavio API.
# Returns structured JSON with comment text, author, score, and more.

SCAVIO_API_KEY="${SCAVIO_API_KEY:-your_scavio_api_key}"
QUERY="${1:-r/ChatGPT best prompt for summarizing long articles}"

curl -s -X POST "https://api.scavio.dev/api/v1/search" \
  -H "x-api-key: $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"r/ChatGPT best prompt for summarizing long articles"}' | python3 -m json.tool

Why Use Scavio Instead of Scraping Reddit Comments Tree Directly?

• No proxy management. Direct scraping requires rotating proxies to avoid IP bans. Scavio handles all of this server-side.
• No CAPTCHA solving. Reddit Comments Tree aggressively blocks automated requests. Scavio returns clean data every time.
• Structured JSON output. No HTML parsing or CSS selector maintenance. Get typed, consistent data from every request.
• Multi-platform in one API. Search Google, Amazon, YouTube, and Walmart from the same API key with the same authentication pattern.
• Free tier included. 500 credits/month with no credit card required. Each search costs 1 credit.
