## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Spain Public Auctions (BOE) — Judicial & Tax Auctions as Clean JSON

**Every public auction in Spain, structured.** Live feed from the official Spanish auction portal (subastas.boe.es): judicial foreclosures, tax-agency and administrative auctions — with the numbers and the asset data investors actually need, one JSON record per auction.

The official portal is a search form with no API. This Actor turns it into data: **"give me every open auction in Madrid with its auction value, minimum bid, deposit, address, cadastral reference and charges."**

### What you get per auction

```json
{
  "id": "SUB-JA-2025-246146",
  "type": "JUDICIAL EN VÍA DE APREMIO",
  "startsAt": "2025-04-18T18:00:00+02:00",
  "endsAt": "2026-07-05T12:27:24+02:00",
  "claimedAmountEur": 6953.30,
  "auctionValueEur": 325095.43,
  "appraisalValueEur": 325095.43,
  "minBidEur": null,
  "bidIncrementEur": 6501.90,
  "depositEur": 16254.77,
  "boeAnnouncement": "BOE-B-2025-13955",
  "url": "https://subastas.boe.es/detalleSubasta.php?idSub=SUB-JA-2025-246146",
  "assets": [
    {
      "description": "VIVIENDA SITA EN C/DEL BARCO Nº27 4ºB MADRID 28004 57 M",
      "cadastralRef": "28108000205725",
      "address": "C/BARCO Nº27 4ºB",
      "postalCode": "28004",
      "city": "MADRID",
      "province": "Madrid",
      "possessionStatus": "No consta",
      "visitable": "No",
      "charges": "SIN CARGAS",
      "registryInfo": "FINCA 2213 REGISTRO DE LA PROPIEDAD Nº27 MADRID"
    }
  ]
}
````

### Market comparison built in (v0.2)

Real-estate auctions are enriched with **live market stats for the asset's own city** (source: fotocasa listings):

```json
"marketComparison": {
  "source": "fotocasa",
  "zoneSlug": "getafe",
  "sampleSize": 31,
  "medianAskingEur": 299000,
  "medianPerM2Eur": 3333,
  "assetSurfaceM2": 75,
  "estMarketValueEur": 249975,
  "estDiscountPct": 34.2
}
```

`estDiscountPct` is the number every auction investor computes by hand: auction value vs what the zone actually asks per m². Note: zone stats come from a first-page sample of asking prices — treat them as a screening signal, then verify. Disable with `compareMarket: false`.

### Why investors use it

- **The spread is visible**: auction value vs appraisal vs minimum bid — the discount math is one subtraction away.
- **Cadastral reference included**: join against Catastro data, comparables or your own models.
- **Charges and possession status**: the two fields that turn a "bargain" into a money pit — surfaced, not buried in a PDF.
- **ISO dates**: bidding deadlines you can sort, filter and alert on.
- **Official source**: the State's own auction portal, every record with its BOE announcement id.

### Use cases

- **Real-estate investors**: daily sweep of open auctions in your provinces, filtered by value band.
- **Proptech / data teams**: structured feed to enrich with Catastro, idealista comps or your AVM.
- **Lawyers / insolvency pros**: track auctions tied to specific proceedings.
- **AI agents**: "find me flats at auction in Madrid under 200k ending this month" — one tool call.

### Input

| Field | Description |
|---|---|
| `status` | `EJ` in progress (default) · `PU` upcoming · `CO` concluded |
| `provinces` | Names or INE codes: `["Madrid", "08"]` — empty for all of Spain |
| `maxAuctions` | Cap per run (default 50) |
| `includeAssets` | Fetch per-auction asset details (default true) |
| `minAuctionValue` / `maxAuctionValue` | Value band filter (EUR) |

### Use with AI agents (MCP)

This Actor is exposed as a tool on the [Apify MCP Server](https://mcp.apify.com):

```json
{
  "mcpServers": {
    "spain-boe-auctions": {
      "url": "https://mcp.apify.com?tools=jdepablos/spain-boe-auctions",
      "headers": { "Authorization": "Bearer <APIFY_TOKEN>" }
    }
  }
}
```

Pairs well with [Spanish Company Feed (BORME)](https://apify.com/jdepablos/borme-company-feed) — same official-source discipline, company events instead of auctions.

### Pricing

Pay per event: **one flat fee per auction returned**, asset details included. Failed fetches are never charged.

### FAQ

**How fresh is the data?** It is scraped live from the official portal at run time — auctions open and close daily; run it on a schedule for monitoring.

**Vehicles and other assets too?** Yes — the portal covers real estate, vehicles and other seized assets. Asset fields adapt (plate/brand/model for vehicles).

**Why is `minBidEur` sometimes null?** "Sin puja mínima" — the auction has no minimum bid, which is exactly the kind you may care about.
