Rebrickable LEGO Set Scraper

Rebrickable LEGO Set Scraper

Scrape LEGO set details from Rebrickable by keyword, theme, or year, up to a million sets per run. Every set comes with its piece count, year, theme, and official Rebrickable data. Export to CSV, JSON, Excel, or XML.

Rebrickable's official API is the definitive source for LEGO set data, but writing code to handle pagination, rate limits, and schema mapping takes time you could spend building. This Actor queries the Rebrickable API directly, filters sets by search terms, theme ID, and year range, and returns each match in one flat, consistent row. No custom integration work required.

Who uses it	What they scrape Rebrickable for
LEGO resellers	Build a live inventory feed with piece counts and release years to price sets accurately.
Data analysts	Pull the complete catalog of a theme across decades to track piece-count trends.
App developers	Populate a LEGO database with official set metadata without managing API integrations.
Collectors	Export a list of every set in a niche theme to track a collection's completion.

What it does

This Actor collects LEGO set records from Rebrickable by keyword search, theme, and year range, and returns each set as a flat row.

• 🔍 Keyword search: enter terms like "star wars" or "castle" and get one result set per term.
• 🏷️ Theme filter: restrict results to a specific Rebrickable theme ID, such as 158 for Star Wars or 1 for Technic.
• 📅 Year range: narrow sets to those released within a min and max year window.
• 📊 Flexible ordering: sort by newest, oldest, name, most parts, fewest parts, or recently updated.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

Troubleshooting

Why am I getting no results?

Check that your search terms match actual LEGO set names and that your theme ID and year range are not too restrictive. Try running with only a search term first, then add filters.

Why is the Actor returning only 10 sets?

Free Apify accounts are limited to 10 items as a preview. Upgrade to a paid plan and increase the Maximum sets field to scrape more.

I'm getting an API key error.

The default shared key may be rate-limited during heavy use. Generate your own free Rebrickable API key from your account settings and replace it in the input.

The theme filter is not working.

Ensure you are using a numeric Rebrickable theme ID, not a theme name. You can find theme IDs by browsing themes on the Rebrickable website.

Results are not sorted as expected.

Confirm the Order by dropdown is set to your preferred sort. The default is newest first. Changing it to Most parts or Name will reorder the output.
