What data can it extract?

How much does it cost to scrape Subastas BOE auctions?

This actor uses pay-per-event pricing.

You pay a small start fee per run and a per-auction result fee for each dataset item saved.

Exact live pricing is shown on the Apify Store actor page.

For first tests, keep maxItems at the prefilled value.

How to scrape active BOE auctions

1. Open the actor on Apify.
2. Leave BOE auction URLs empty.
3. Leave BOE auction IDs empty.
4. Set Maximum auctions to a small number such as 10.
5. Keep BOE status code as EJ for auctions in progress.
6. Click Start.
7. Export results from the Dataset tab.

How to scrape known auction IDs

Paste identifiers such as:

SUB-JA-2025-234719

The actor converts them to BOE detail URLs and extracts public details.

How to scrape BOE detail URLs

You can also paste URLs like:

https://subastas.boe.es/detalleSubasta.php?idSub=SUB-JA-2025-234719

This is useful when you already collect BOE links from another system.

Input options

BOE auction URLs

Optional list of BOE detail URLs.

BOE auction IDs

Optional list of BOE identifiers.

Maximum auctions

Caps the number of records saved.

BOE status code

Default is EJ, which means auctions currently in progress.

Fetch detail tabs

When enabled, the actor fetches public BOE tabs for general details, managing authority, assets, related notices, and public bid summary.

Output example

{
"id":"SUB-JA-2025-234719",
"url":"https://subastas.boe.es/detalleSubasta.php?idSub=SUB-JA-2025-234719",

Tips for better results

• Start with active auctions (EJ) and low maxItems.
• Use auction IDs when monitoring a watchlist.
• Keep includeDetails enabled when you need values, deposits, and assets.
• Disable detail tabs only when you need a fast listing preview.
• Always review BOE source URLs before making investment decisions.

Data quality notes

The actor only extracts fields that BOE makes public without logging in.

Some complementary documents or bidder actions may require a BOE account and are not scraped.

Spanish date strings are preserved, and ISO values are extracted when BOE includes them in the page.

Limitations

• Login-only complementary files are out of scope.
• BOE can change public status codes or page markup.
• Asset text can be long because legal descriptions are verbose.
• The actor does not provide legal, investment, or valuation advice.

Legality

This actor collects publicly visible information from an official public website.

You are responsible for using the data in compliance with applicable laws, BOE terms, and privacy obligations.

Do not use the actor to access account-only bidder workflows.

FAQ

Why did I get zero results?

The selected BOE status code may have no current auctions. Try EJ or provide known auction IDs.

Why are some values null?

BOE sometimes writes values as "Sin puja mínima", "Sin tramos", or omits fields. The actor returns null for those numeric fields.

Why is the asset text long?

BOE legal descriptions often include registry, location, possession, charges, and other legal wording in one public block.
