Integration

How to run it

The same lookup works from the app, the API, or as a tool an agent can call mid-task.

Results come back in the same envelope as every other source: a session id, a readable summary, the structured result and the points charged.

curl -X POST https://api.neuralverge.ai/functions/v1/run-kr-company-filings \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"company":"00126380","max_items":2}'
Use cases

Where this field shows up in an actual workflow.

Monitoring disclosures

Pull the latest filings for a listed company and react to ownership or other material reports.

Tracking insider activity

See ownership reports filed by directors and major shareholders.

Due diligence

Review a company's recent reporting history in one list.

Coverage & limits

Coverage, freshness and limits

What this source covers, how fresh it is, and where it stops.

Coverage

South Korea — entities on DART.

Freshness

Read at request time, so the answer reflects the register as it stands when you ask.

Handling

DART is a public register. Every response carries the source URL it was read from and a session id you can trace.

What it will not do
  • —Report names and remarks are in Korean.
  • —The list gives each report's metadata and link, not the report's contents.
  • —Several fields repeat the company-style layout and are empty for filings, as the sample shows.
