Korea Company Data — developer kit

Paused — data available on request. The REST API, the MCP server and sign-up are switched off for now, so the CLI and MCP server here cannot fetch anything at the moment. The data is not gone: it can be provided on request. Email support@notonlystock.com with what you need — which companies or rail data, which fields, and in what form — or leave a note on the feedback page. The data guide and API reference stay up, and existing keys and credits are kept for when the API reopens.

Korean company records in English: identity, registration status, industry, address, and month-by-month employment from government payroll records.

Plus nationwide rail — every subway and commuter-rail stop, route and departure, eleven operators reconciled into one GTFS-shaped dataset.

Three ways in, one API key.

Keys are issued at **https://dataservice.notonlystock.com/korea/account** once the API reopens — 5,000 free credits, no card.

What is in the data

152,367 Korean for-profit corporate headquarters with 10 or more insured employees.

FieldPresent
Employees (Employment Insurance)100%
Address in English100%
Established date100%
Monthly employment series91.9%
Corporate registration number70.5%
Phone69.3%
Listed market · DART code25.5%
Worksite addresses with headcount100% (25.5% have more than one)

Registration numbers are validated against the National Tax Service. Where a value could be read as more than it is, a companion field says what kind of value it is — name_en_class, established_date_source, nps_quality. Which source each field comes from is in the data guide.

What this does not do

No score, no grade, no ranking, no opinion about any company. No sanctions, penalties or litigation history. No personal data. Facts and their sources only.

Stability

The API is v0. Paths, parameters and field names may change without notice until v1. Pin nothing you cannot change.
