How this service works

한국 HS854232 무역 통계, 코스닥 OpenDART 7일 공시 목록과 Base ERC-20 계약 기초 사실의 무료 목록·샘플 및 x402 고정 버전 JSON API.

Output

A JSON object containing: the product ID, version timestamp, market/collection scope, coverage metadata (source URL, date range, observation timestamp, page count, total record count of 745, completeness flag, SHA-256 hashes per page), and an array of KOSDAQ corporate disclosure records from OpenDART spanning the 7 days prior to the snapshot.

Example use cases

Weekly KOSDAQ disclosure monitoring

“Get me the latest KOSDAQ OpenDART 7-day filing snapshot so I can see all corporate disclosures filed on the Korean stock exchange this week, including the cryptographic hashes to verify data integrity.”

Compliance audit of Korean filings

“I need to audit KOSDAQ corporate disclosures for the period ending October 8, 2026 — fetch the versioned OpenDART snapshot (version 20261008T004559Z) with all 745 records and the SHA-256 evidence for each paginated source page.”

Financial research data ingestion

“Download the complete KOSDAQ OpenDART filings list from the snapshot dated October 2–8, 2026 so I can analyze what Korean companies published regulatory disclosures during that window.”

Endpoint

GEThttps://kmde-snapshot-candidate.onrender.com/v1/opendart/kosdaq/20261008T004559Z/all.json?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a cryptographically verifiable, immutable snapshot of all KOSDAQ OpenDART corporate disclosures over a 7-day window, particularly when auditability (SHA-256 page hashes) and a fixed version reference matter. Prefer this over live OpenDART API calls when you want a stable, repeatable dataset without rate-limit concerns on the FSS API. Best for batch ingestion, compliance review, or research pipelines that require a frozen record of Korean KOSDAQ filings from this specific period.

Side effects

Version mismatch — requesting a version string other than the fixed '20261008T004559Z' will likely return 404 or no data, as the endpoint is pinned to a specific snapshot
Service unavailability — hosted on Render free tier (render.com), which may spin down and return 502 or timeout after inactivity
Payment failure — x402 micropayment of $0.005 USDC not completed results in 402 response with no data
Partial current-day data — the snapshot notes current_day_partial=true, meaning filings on the snapshot date may be incomplete
pagination_atomic=false — the snapshot was not captured in a single atomic operation, so there is a small risk of inconsistency across the 8 pages
