Korean Tickers is built as source-labeled research infrastructure. It is not a broker, trading terminal, or investment adviser.
Korean stock and index quote snapshots refreshed every 30 minutes where configured. These are not presented as a real-time or streaming trading feed; data.go.kr daily files remain the fallback and history source.
SourceDaily public price, index, issuer, and listed-company reference data. Price files update after the next trading day.
SourceOfficial Korean corporate disclosure records and financial statement data.
SourceEnglish filing metadata and English viewer support where available.
SourceKorean macro indicators, rates, CPI, and USD/KRW reference data.
SourceThe Standard API is filing-backed, not a live market feed. Its contract separates reported facts, official DART indicators, and Korean Tickers derived values while preserving nulls and source lineage.
DART/OpenDART filing records and financial statements are authoritative for filing-derived facts. Korean Tickers does not replace the original filing.
Stable English metric keys map issuer-specific DART/XBRL accounts into a documented catalog. Raw source account IDs/names and mapping lineage are retained when available; derived values carry input keys and formula expressions.
The API identifies fiscal period, report code, and consolidated (CFS) or separate (OFS) scope. Consumers should not compare values across scopes without checking these fields.
Unavailable or non-applicable facts remain null with an availability or missing-reason signal. They are not converted to zero.
Monetary facts use unit=currency plus their source ISO currency. Percentage points and ratio multiples use unit=pct or unit=ratio with currency=null. No currency conversion is implied.
A corrected or newly processed filing can change normalized output. Receipt numbers and source links let consumers reconcile a response with the underlying filing.
Display-label precedence is exact official English OpenDART line, latest official English taxonomy label, canonical metric label, then account-ID/source fallback. Korean raw statement/account/detail labels remain separate provenance fields; machine-translated raw labels are not presented as official source text.
Data refreshes after a DART filing is collected and normalized. No publication-to-API latency is guaranteed during the manual pilot. Check source receipt and period fields rather than treating response generation time as the filing date.
Upstream DART services can revise limits, return no-data responses, pause for maintenance, or delay source availability. Those upstream states are distinct from Korean Tickers collection and normalization timestamps.

For API-derived financial facts, retain the ticker, fiscal period, report code, statement scope, DART receipt number or source URL, and the reported account or derived formula metadata supplied with the response. Original filings are prepared by issuers, and DART does not guarantee their accuracy or completeness.
