What does market_tag mean?

It is the one-character market marker DART shows beside a company. The company_type field spells the market out.

Do I pay for lookups that come back empty?

No. You are charged per result, so a request that finds nothing costs nothing. Testing this against a messy list is free to get wrong.

What does a lookup cost?

1 point per returned record, which is $1 per 1,000, and only records that come back are charged. Points come out of your monthly plan allowance, so there is no separate per-country contract.

You get back: Matching companies with DART corp code, name, market, stock code and a link to each record
Coverage: South Korea — entities on DART.
Price: 1 point per returned record — $1 per 1,000; Billed per record actually returned, capped by max_items. A request that returns nothing costs nothing.

Comparison

Ways to get this data

Three approaches teams use today, and where each one runs into trouble.

Approach	What it takes	Cost	Trade-off
DART directly	Type the name into DART and read the results	Usually free, sometimes per-document	A different interface, language and data shape for every country you add
Collecting it yourself	Build and host a crawler per register, then keep each one alive	Infrastructure and maintenance	Registers change their pages without warning, and nobody is on the hook when yours breaks
NeuralVerge	One request, the same shape as every other source in the catalog	$1 per 1,000, misses not billed	Covers South Korea — other countries are separate sources with the same request format

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-companies-search \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"keyword":"삼성전자","max_items":2}'

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

—Status, address and established date are empty in search results; use the company lookup for them.
—The register is DART, so companies that do not report there will not appear.
—Names are in Korean, and the example keyword is Korean.
