# Fraud Prevention Center (CPF)

> Argentina CPF lookups by CUIT and recipient CBU/CVU via Gu1 marketplace service ar_gueno_cpf_service.

## Overview

**Integration code:** `ar_gueno_cpf_service`

Marketplace name: **Central de Prevención de Fraude** (CPF). Aligned with BCRA Com. «A» 8298 (Sistema Nacional de Pagos). Distinct from BCRA Central de Deudores (`ar_bcra_deudas_enrichment`).

Gu1 proxies the CPF corpus on your behalf. Integrators **do not** call holder-score directly.

**Access:** the catalog entry is live but **paused globally by default**. Gu1 must exempt your organization from the pause and you enable the integration in Marketplace before API calls succeed.
