## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Spain Tax ID Validator — NIF, CIF, NIE, IBAN & EU VAT (VIES)

Batch-validate **Spanish tax IDs** (NIF/DNI/NIE/CIF with official check-digit algorithms), **IBANs** (mod-97, 30 countries) and **EU VAT numbers** against the **official European Commission VIES API** — with auto-detection, caching, and retries built in. Send a mixed list, get clean JSON back. Built for **AI agents, n8n, Make, Zapier and ERP integrations**.

### Why this Actor

- **One call, mixed input.** Auto-detects whether each value is a DNI, NIE, CIF, IBAN or EU VAT number. No pre-sorting, no per-type endpoints.
- **VIES made reliable.** The official VIES service rate-limits per country and goes down by national node. This Actor adds retries with exponential backoff and a **24h cache — cache hits are free** (not charged).
- **Fair pricing.** Local validations (NIF/IBAN) cost $1 per 1,000. VIES checks $4 per 1,000. Failed VIES lookups and unrecognized inputs are **never charged**.
- **Audit-ready.** Pass your own VAT (`options.requesterVat`) and every VIES check returns an official **consultation number** — the legal proof of validation under Art. 138 of the VAT Directive.

### Use cases

Customer/supplier onboarding (KYB), invoice validation before payment, e-commerce B2B checkout (VAT-exempt intra-EU sales), CRM data cleaning, accounting automation, agent workflows that need to verify a Spanish company exists before acting.

### Input

```json
{
    "values": ["12345678Z", "ES91 2100 0418 4502 0005 1332", "ESB12345674", "DE811907980"]
}
````

Spaces, dots and dashes are ignored. Optional: `items` with forced types, `options.vies` (default `true`), `options.cacheTTLHours` (default `24`), `options.requesterVat`.

### Output (one row per value)

```json
{
    "input": "DE811907980",
    "type": "eu-vat",
    "valid": true,
    "normalized": "DE811907980",
    "reason": null,
    "details": { "viesName": "...", "viesAddress": "...", "consultationNumber": "WAPIAAAAW..." },
    "source": "vies",
    "checkedAt": "2026-07-03T02:00:00.000Z"
}
```

`reason` is a stable machine-readable enum prefix (`FORMAT`, `CHECK_LETTER`, `MOD97`, `VIES_ERROR`, ...) — branch your automation on it without parsing prose.

### Pricing (pay-per-event)

| Event | Price | Notes |
|---|---|---|
| Actor start | $0.005 | per run |
| NIF/DNI/NIE/CIF validated | $0.001 | local check-digit |
| IBAN validated | $0.001 | local mod-97 |
| EU VAT validated (VIES) | $0.004 | real VIES call; **cache hits & failures free** |

Validating 1,000 Spanish tax IDs costs ~$1. No subscription, no API key.

### Using from AI agents (MCP)

This Actor works out of the box with the [Apify MCP server](https://mcp.apify.com) — Claude, ChatGPT, Cursor or any MCP client can call it as a tool.

### FAQ

**Does the developer see or store my data?** No. Results live in **your** run's dataset and the VIES cache is a key-value store **in your own Apify account** (TTL-limited, default 24h). Nothing is sent to or retained by the developer.

**What if VIES is down?** The Actor retries (1s/3s/9s backoff). If still down, the row returns `valid: null` with a `retryable` flag — and you are not charged for it.

**Which countries?** Tax IDs: Spain. IBAN: 30 European countries. VAT: all 27 EU member states + XI (Northern Ireland).

### ¿Trabajas con datos españoles?

Este actor valida **NIF, DNI, NIE y CIF** con los algoritmos oficiales de dígito de control, **IBAN** y **IVA intracomunitario contra el VIES** (con caché y reintentos incluidos — los cache hits no se cobran). Pensado para gestorías, e-commerce B2B, onboarding de proveedores y flujos de n8n/Make/Zapier o agentes de IA. Pásale una lista mezclada: detecta el tipo de cada valor automáticamente.

# Actor input Schema

## `values` (type: `array`):

Mixed list of identifiers — type is auto-detected. Accepts Spanish NIF/DNI/NIE/CIF, IBANs and EU VAT numbers (e.g. ESB12345674, DE811907980). Spaces, dots and dashes are ignored.

## `items` (type: `array`):

Alternative to 'values': objects like {"value": "B12345674", "type": "cif"} when you want to force the type instead of auto-detecting it.

## `options` (type: `object`):

vies (bool, default true): call the official VIES API for EU VAT numbers. cacheTTLHours (number, default 24): VIES cache window — cache hits are NOT charged. requesterVat (string): your own EU VAT to get an official VIES consultation number (legal proof).

## Actor input object example

```json
{
  "values": [
    "12345678Z",

    "ESB12345674"
  ],
  "options": {
