Overview

The ThredUp Product Search Scraper extracts detailed product information from ThredUp's searchable catalog pages. It transforms dynamic search results into clean, structured datasets containing pricing, availability, brand details, condition ratings, and more.

The scraper is ideal for:

• Fashion retailers tracking secondhand market trends and competitor pricing
• Resellers monitoring inventory availability and price fluctuations
• Data analysts building historical datasets for fashion market research
• Price intelligence platforms aggregating secondhand valuations
• Sustainability researchers analyzing the pre-owned fashion ecosystem

Key features include configurable item limits, resilient URL handling, and batch scraping across multiple department and search filters.

Input Format

The scraper accepts a JSON configuration with three core parameters:

{
  "urls": [
    "https://www.thredup.com/women?department_tags=women&page=2"
  ],
  "ignore_url_failures": true,
  "max_items_per_url": 200
}

Input Parameters Explained

Parameter	Type	Description
urls	Array	Product search page URLs from ThredUp. Include full query strings (filters, page numbers, department tags) for precise targeting. Example: /women?department_tags=women&page=2
ignore_url_failures	Boolean	If true, the scraper continues running even if some URLs fail. Useful for bulk operations where occasional failures shouldn't halt the entire job.
max_items_per_url	Integer	Maximum number of products to extract from each URL (e.g., 200 scrapes up to 200 items per page). Balances thoroughness with performance.

Best Practices

• Build URL lists using ThredUp's search filters (department, brand, size, price range) to target specific product segments.
• Use pagination carefully — each page parameter adds one URL; avoid excessive pages to prevent rate-limiting.
• Test URLs first — verify a single URL returns products before batching hundreds.

How to Use

1. Identify target URLs — Navigate to ThredUp.com and apply search filters (department, brand, size, price). Copy the filtered search page URL including all query parameters.

2. Build the configuration — Create your JSON input with one or more URLs. For example:

{
     "urls": [
       "https://www.thredup.com/women?department_tags=women&price=0-50&page=1",
       "https://www.thredup.com/women?department_tags=women&price=0-50&page=2"
     ],
     "max_items_per_url": 100,
     "ignore_url_failures": true
   }

3. Run the scraper — Submit the configuration and monitor progress.

4. Export results — Download output in JSON, CSV, or Excel format for analysis.

Troubleshooting:

• If results are empty, verify the URL loads products in your browser.
• ThredUp may rate-limit aggressive scraping; reduce max_items_per_url or spread requests over time.
• Use ignore_url_failures: true when batching 10+ URLs to tolerate occasional connection issues.
