💎 Using Ruby

Overview

Learn how to scrape Reddit search results using Ruby. This comprehensive guide will walk you through the entire process, from setup to implementation.

What You'll Learn

  • • Setting up your development environment
  • • Installing the required HTTP client
  • • Authenticating with the ScrapeCreators API
  • • Making requests to Reddit
  • • Handling responses and errors
  • • Best practices for production use

What You'll Get

  • • Access to search results data
  • • JSON formatted responses
  • • Real-time data access
  • • Scalable solution
  • • Error handling patterns
  • • Performance optimization tips

Prerequisites

1. API Key

First, you'll need a ScrapeCreators API key to authenticate your requests.

Sign up at app.scrapecreators.com to get your free API key with 100 requests.

2. Development Environment

Make sure you have the following installed:

  • • Ruby and its dependencies
  • • A code editor (VS Code, Sublime, etc.)
  • • Basic understanding of API requests
  • • Command line interface access

Step 1: Install HTTP Client

HTTParty is a Ruby library that makes HTTP requests easy

gem
gem install httparty

Step 2: API Implementation

Now let's make a request to the Reddit API using Ruby. Replace YOUR_API_KEY with your actual API key.

Ruby
require 'httparty'
require 'json'

API_KEY = 'YOUR_API_KEY'

def scrape
  response = HTTParty.get(
    "https://api.scrapecreators.com/v1/reddit/search",
    headers: {
      'x-api-key' => API_KEY,
      'Content-Type' => 'application/json'
    },
    query: {
        'query' => 'example_value',
      'sort' => 'relevance',
      'timeframe' => 'all',
      'after' => 't3_1i8z28z',
      'trim' => 'false'
    }
  )

  puts 'Response:'
  puts JSON.pretty_generate(response.parsed_response)
  response.parsed_response
rescue => e
  puts "Error: #{e.message}"
  nil
end

# Usage
result = scrape

Step 3: Testing Your Code

API Parameters

This endpoint accepts the following parameters:

queryRequired(string)

Search query

sortOptional(select)

Sort by

Example: relevance

timeframeOptional(select)

Timeframe

Example: all

afterOptional(string)

Used to paginate to next page

Example: t3_1i8z28z

trimOptional(boolean)

Set to true for a trimmed down version of the response

Example: false

Run Your Code

Execute your script to test the API connection. You should see a JSON response with Reddit search results data.

✅ Success: You should receive a structured JSON response containing the requested data.

Verify Response Structure

Check that your response includes the expected fields:

  • ✓success(boolean)
  • ✓posts(object)
  • ✓after(string)

Best Practices

1

Error Handling

Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.

2

Caching

Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.

3

Security

Never expose your API key in client-side code. Use environment variables and secure key management practices.

Performance Tips

Batch Requests

When scraping multiple search results, consider batching requests to maximize throughput while staying within rate limits.

Async Processing

Use asynchronous processing in Ruby to handle multiple requests concurrently and improve overall performance.

Common Use Cases

Market Research

Analyze Reddit search results to understand market trends, competitor analysis, and audience insights.

Content Analytics

Track performance metrics, engagement rates, and content trends across Reddit search results.

Lead Generation

Identify potential customers and business opportunities throughReddit data analysis.

Troubleshooting

Common Errors

401 Unauthorized

Check your API key is correct and properly formatted in the x-api-key header.

402 Payment Required

You ran out of credits and need to buy more.

404 Not Found

The resource might not exist or be private.

500 Server Error

Temporary server issue. Implement retry logic with exponential backoff.
