How do I get a Rebrickable API key?

Visit [**rebrickable.com/api**](https://rebrickable.com/api/), sign in with your Rebrickable account, and your API key will be displayed on the page. Copy it — it's a long alphanumeric string.

Can I search for sets by theme?

Yes! Use `list_sets` with `theme_id` to filter by theme. First use `list_themes` to find the theme ID (e.g. Star Wars = 170), then pass it to list_sets. You can also filter by year or part number.

Can I see the parts inventory for a set?

Yes! Use `get_set_parts` with the set number (e.g. "75192-1" for the Millennium Falcon). Returns every part with its part number, color ID, quantity and whether it's a spare. Set inc_minifig_parts to true to include minifig parts.

How many results can I get at once?

The API supports up to 1000 results per request. Use the `page_size` parameter (max 1000, default 100) and `page` for pagination. The total count and next/previous URLs are returned in each response.
