A company's file is scattered across registries that do not talk to each other

In Colombia the chamber of commerce knows who the legal representative is, Supersociedades holds the financial statements, SECOP says which public contracts it won and SICAAC whether it entered reorganization. In Peru SUNAT summarizes the status and condition of the RUC; in Mexico SIEM records the establishment; in Brazil PGFN, TST and Caixa certify whether it owes the treasury, its workers or the FGTS; in the United States every state keeps its own registry and the SEC publishes who raised capital.

Croma queries each registry with the identifier you already have (NIT, RUC, CNPJ or the state's registration number) and returns a JSON with the same shape in every country. What used to be an analyst opening six portals becomes one call.

How it works

From the question to the JSON in three steps

  1. 01

    Send the identifier

    A NIT without its check digit, an 11-digit RUC, a CNPJ or the state registration number. If you only have the name, the search by legal name returns the candidates with their identifier.

  2. 02

    Receive the structured record

    Legal name, registration or RUC status, economic activity, address, legal representatives and, where the source publishes them, financial figures by year.

  3. 03

    Decide on the crossed signals

    A cancelled registration, a RUC not found at its address, an open reorganization or a sanction as a state contractor change the decision. Each signal arrives from its own source, with provenance.

What you send and what you get

Each row is an API endpoint. The input is what your system already holds; the output, the fields the official registry returns.

Three possible answers

  • 01

    Found

    The record exists and arrives structured, with the fields in the table and the source that produced it.

  • 02

    No record

    The source has nothing for that identifier. It is a definitive answer (found: false), not an error.

  • 03

    Pending

    Slow sources return a job with a status_url to poll for the result, or deliver it to your webhook.

Where it runs

Where teams use it

  • Account opening and onboarding

    Validate legal existence and the representative before onboarding a business customer, with the same flow in Bogotá, Lima or Mexico City.

  • SME lending

    Cross the commercial registration with reported financial statements and insolvency to size the risk before disbursing.

  • Suppliers and counterparties

    Before signing, confirm the company exists, is active and carries no sanctions as a state contractor.

  • AI agents

    An agent connected over MCP asks who owns this NIT and receives the official record, not a web summary.

Trust

Official records, with provenance

  • Official sources only

    Every answer names the official registry that produced it. Nothing comes from purchased databases or third-party summaries.

  • Results that are never indexed

    In the free tools the query and the result live in your browser, never in a URL. In the API: encryption in transit, access control and audit logging.

  • Personal data, with rules

    Lookups on individuals require a legitimate purpose under each country's law: Ley 1581 in Colombia, LFPDPPP in Mexico, Ley 29733 in Peru, LGPD in Brazil. Croma delivers the record; the purpose and the legal basis are yours.

  • A stable contract

    Every field is documented in the OpenAPI, with a 90-day deprecation policy and Deprecation and Sunset headers before anything is retired.

Frequently asked questions

The country's: NIT in Colombia, RUC in Peru, CNPJ in Brazil, the state's document or file number in the United States. In Mexico SIEM is queried by name and by establishment id. If you only have the name, the search endpoints return the candidates with their identifier.

The structure is: every endpoint returns found, the record under data and its provenance. The fields change with what each registry publishes; a RUC has no financial statements and a Colombian registration has no habido condition. Every field is documented in the OpenAPI.

No. It is the informational lookup of the registry, in real time, to decide quickly. The legally valid certificate is issued by the chamber of commerce; Croma tells you whether it is worth requesting.

The endpoint answers found: false. It is a definitive answer from the source, not an error, and it counts as a single query.

Yes. The API accepts batches on the endpoints that support them, and long jobs return a status_url or call your webhook. For high volumes, book a demo and we design the flow with you.

Verification answers who the company is; screening, whether it or its officers carry sanctions, records or cases. They are separate requests on the same key and usually run together.
