The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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 ## Polish VAT Whitelist & Bank Account Validator Batch-check Polish supplier bank accounts against the official Ministry of Finance VAT Whitelist API. This Actor verifies whether a Polish bank account is assigned to a NIP or REGON on a chosen date and returns the official `requestId` from the MF API. It is designed for accounting, compliance, supplier checks, and audit trails. ### Input ```json { "verificationDate": "2026-06-30", "maxChecks": 100, "includeFullBankAccount": false, "records": [ { "reference": "invoice-001", "identifierType": "nip", "identifier": "5260250274", "bankAccount": "18101014690032611391200000" } ] } ```` You can also use `nip` or `regon` fields directly instead of `identifierType` + `identifier`. ### Output Each dataset item contains: - input reference, - identifier type and normalized identifier, - masked bank account, - official `accountAssigned` result (`TAK` / `NIE`), - boolean `isAssigned`, - MF `requestId`, - MF request time, - error details for failed checks. Full bank account echo is disabled by default. Enable `includeFullBankAccount` only when you need it for your own audit export. ### Source And Limits Official source: `https://wl-api.mf.gov.pl`. The Ministry of Finance states that the simplified `check` method is limited to 5000 entities per day. This Actor keeps a per-run `maxChecks` cap and avoids scraping or enrichment. ### Disclaimer This Actor is not an official service of the Polish Ministry of Finance and does not provide tax advice. It calls the public MF API and returns the response for automation and audit convenience. # Actor input Schema ## `records` (type: `array`): Each record needs a NIP or REGON identifier and a Polish bank account number. ## `verificationDate` (type: `string`): Date used by the MF API in YYYY-MM-DD format. Defaults to today. ## `maxChecks` (type: `integer`): Hard cap for one run. Keep this below MF public API limits. ## `includeFullBankAccount` (type: `boolean`): Off by default. Output uses masked account numbers unless you explicitly need full audit echo. ## `sourceMode` (type: `string`): Use offline for local fixture-based checks. ## Actor input object example ```json { "records": [ { "reference": "mf-demo", "identifierType": "nip", "identifier": "5260250274", "bankAccount": "18101014690032611391200000" } ], "maxChecks": 100, "includeFullBankAccount": false, "sourceMode": "live" } ``` # Actor output Schema ## `results` (type: `string`): Dataset items with identifier, masked bank account, official TAK/NIE result, MF request ID, request time, and error details when a check fails. ## `summary` (type: `string`): Run summary stored in the default key-value store under the OUTPUT key. # API You can run this Actor programmatically using our API.
