How to Scrape Redfin with cURL

Redfin contains valuable data -- price, beds, baths, sqft, structured address, days_on_market, medians block for the result set, 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 Redfin using cURL and the Scavio API. By the end, you will have a working cURL script that fetches real-time Redfin 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 50 credits on signup -- no credit card required)

Step 1: Install Dependencies

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

# cURL is pre-installed on macOS, Linux, and Windows 10+

Step 2: Make Your First Redfin Search

Send a POST request to the Scavio Redfin API endpoint with your query. The API returns structured JSON with price, beds, baths, sqft, structured address, days_on_market, and more.

# This page has no dedicated endpoint yet, so the sample runs a Google web search.
curl -X POST "https://api.scavio.dev/api/v2/google" \
  -H "Authorization: Bearer sk_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"query":"https://www.redfin.com/city/30818/TX/Austin"}'

Step 3: Example Response

The API returns structured JSON. Here is an example response for a Redfin search:

{
  "search_parameters": { "q": "cold brew coffee", "hl": "en", "gl": "us" },
  "organic_results": [
    {
      "position": 1,
      "title": "how do you guys make cold brew? : r/Coffee",
      "link": "https://www.reddit.com/r/Coffee/comments/oi7rm7/how_do_you_guys_make_cold_brew/",
      "snippet": "i wanna learn how to make cold brew coffee but theres a lot of ways...",
      "source": "Reddit"
    }
  ],
  "related_searches": [{ "query": "cold brew ratio", "link": "https://www.google.com/search?q=cold+brew+ratio" }],
  "response_time": 2841,
  "credits_used": 1,
  "credits_remaining": 4821
}

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 Redfin and prints the results:

#!/bin/bash
# Search Redfin data with the Scavio API.
# POST /api/v2/google - rows come back under organic_results.
# This page has no dedicated endpoint yet, so the sample runs a Google web search.

SCAVIO_API_KEY="${SCAVIO_API_KEY:-sk_live_your_key}"
INPUT="${1:-https://www.redfin.com/city/30818/TX/Austin}"

curl -s -X POST "https://api.scavio.dev/api/v2/google" \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"query\":\"$INPUT\"}" | python3 -m json.tool

Why Use Scavio Instead of Scraping Redfin Directly?

• No proxy management. Direct scraping requires rotating proxies to avoid IP bans. Scavio handles all of this server-side.
• No CAPTCHA solving. Redfin 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. 50 credits on signup with no credit card required. Each search costs 1 credit.
