Argentina Company Check (CUIT) — KYB & due diligence MCP

Argentina Company Check (CUIT)

Check companies in Argentina by their CUIT (tax identification number) in one call and get a clean English JSON answer with red flags, source attribution and a date on every field. Built for AI agents (MCP) and for KYB / AML onboarding, counterparty and supplier due diligence, vendor risk and compliance checks.

• One number → one answer from official open registers plus GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions and Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only.
• One schema for every country: the same fields and flags whether you check one Argentina company or a thousand — your agent parses one format.
• Agent-ready: an MCP server (Streamable HTTP, /mcp) with check_company, check_companies and list_sources, a plain GET /check?country=&id= endpoint, and classic batch runs (list of numbers → dataset).
• Change history: registers publish only the current state; we keep our own snapshots, so every answer shows what was added or removed since history_since (e.g. a status change or a new sanctions listing).
• Pay per check (one charge per company answered; the price is on the Pricing tab), no subscription. Malformed numbers, sole traders and individuals are not charged. In Standby (MCP / HTTP) mode Apify also bills the small platform usage of the server run, as for every Standby Actor. Set a maximum cost per run in Apify to cap spending: when it is reached, the Actor returns an error instead of data.

Data refreshed at least weekly; every field carries its source date (provenance), and every answer lists each source with the date it was loaded (sources[].loaded_at; list_sources is free).

flags — true is a red flag: not_found (the number is not in the register dump), not_active, insolvency, liquidation, sanctions (match by registration number or LEI), sanctions_name_match (same name, same country: verify manually). false means there is no record in the loaded snapshot — it is not a clean bill of health. null means unknown. Call list_sources (free) for load times.

Argentina: Legal entities with a CUIT in the national companies register (RNS, from the ARCA federal register of legal persons): companies, cooperatives, associations, foundations, foreign companies and branches, including dissolved ones. Joint ventures (UTE), trusts and natural persons are not in it, so a CUIT with no record is reported as unknown and not charged. A valid CUIT without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Not affiliated with or endorsed by the Ministry of Justice of Argentina, ARCA or the Inspección General de Justicia (IGJ). Data from the Registro Nacional de Sociedades (monthly snapshot of the ARCA federal register of legal persons) and the IGJ register of entities, both published on datos.jus.gob.ar under CC BY 4.0. Status: the national register does not publish a status, so it is unknown unless the entity is registered with the IGJ (Buenos Aires City): then dissolved (cancelled, merged, liquidated), in_liquidation (liquidation in progress), inactive (in the IGJ register of inactive entities for another reason) or active; a move to a provincial registry or a transformation stays unknown. flags.fiscal_address_not_found is true when ARCA marks the fiscal address as non-existent or unknown (INEXISTENTE - DESCONOCIDO). flags.insolvency is true only where IGJ cancelled the entity for bankruptcy, otherwise null: there is no open bulk copy of the bankruptcy register. Addresses are city level only; partnerships whose names contain partners' names are legal entities and are returned like any company.
