Checko

Checko due diligence on Russian companies and entrepreneurs (EGRUL, EGRIP): company details, directors and founders, contacts, financial statements, reliability score, arbitration cases, enforcement proceedings, public procurement contracts, Fedresurs and bankruptcy messages, inspections, banks and search. Read-only.

Setup

Setting up takes about 2 minutes. You need a Checko account; the API key comes with it.

1. Register at https://checko.ru and open your personal account (Личный кабинет). The API key is shown there right after registration.
2. Paste it into CHECKO_API_KEY. The connector sends it as the key query parameter.
3. Install the connector and run checko_get_bank: the install check reads Sberbank (BIC 044525225) and shows that the key works.

Identifiers: an INN has 10 digits for an organisation and 12 for an entrepreneur or a private person; an OGRN has 13 digits (organisation), an OGRNIP 15 (entrepreneur). Most tools take inn or ogrn, and one of them is enough. A branch shares the INN of its head organisation, so the head organisation is what comes back.

What it reads: organisations from EGRUL and entrepreneurs from EGRIP with status, registration, legal address, OKVED activity codes, directors, founders and their shares, related companies, licences, branches, contacts, taxes and tax debts, SME register entries, risk factors and sanctions; the business links of a private person by personal INN; financial statements by line code; a reliability assessment with positive and negative factors; the history of register changes; arbitration court cases; FSSP enforcement proceedings; public procurement contracts under 44-FZ, 94-FZ and 223-FZ; Fedresurs messages and EFRSB bankruptcy messages; state inspections; and Russian banks by BIC from the Bank of Russia directory.

How the AI works with it: to find a company it searches with checko_search (a name of at least 4 characters, or a director, founder, phone, e-mail, OKVED code or registration date) and then reads the result with checko_get_company by INN. For due diligence on a counterparty it combines checko_get_company, checko_get_reliability, checko_get_finances (revenue is line 2110, net profit line 2400), checko_list_legal_cases with the role defendant, checko_list_enforcements, checko_list_bankruptcy_messages, checko_list_fedresurs_messages and checko_list_inspections. For public procurement it filters checko_list_contracts by law 44, 94 or 223 and by role customer or supplier.

Read-only: all 14 tools only read. Nothing is filed or changed, so there is nothing to confirm and no tool is switched off at install.

Paging: list tools return up to 100 rows per page (limit, page) together with the total count. Every answer carries meta with the status, the number of requests made today and the account balance in roubles.

Costs and limits: the first 100 requests a day are free on every plan; after that each successful request (HTTP 200) is billed at the plan price, from 0.10 to 0.15 roubles, and errors are free. The technical limit is 32 requests per second per IP address. The AI prefers one targeted call over many broad ones.

Common errors: 401 with meta.message means a missing or invalid key. 402, or a message about the balance, means the free daily quota is used up and the balance is empty. 404 means nothing was found for that INN or OGRN. Error answers carry meta.status error and the reason in meta.message, in Russian.

The connector does not cover companies from Belarus, the raw EGRUL source data or Checko's bulk datasets.
