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 structured JSON object containing: market scope metadata (KOSDAQ_ALL, 7-day period), version timestamp, coverage details (source URL, date range, SHA-256 hashes per paginated page with observation timestamps, total page count, quarantine count), and the full list of KOSDAQ disclosure filings sourced from OpenDART's public API.

Example use cases

KOSDAQ Regulatory Filing Audit

“Give me the complete list of all KOSDAQ company disclosures filed with OpenDART for the week of October 2–8, 2026, including the cryptographic hashes for each page so I can audit the data provenance.”

Korean Equity Research Data Feed

“I'm researching KOSDAQ companies — fetch the full OpenDART disclosure snapshot from October 8, 2026 so I can see every corporate announcement filed that week across the whole market.”

Compliance Monitoring for KOSDAQ Holdings

“Pull the KOSDAQ OpenDART 7-day filing snapshot ending October 8, 2026 and tell me how many filings were collected and what the coverage period was — I need this for our weekly compliance report.”

Technical details

Endpoint

GEThttps://kmde-snapshot-candidate.onrender.com/v1/opendart/kosdaq/20261008T124737Z/all.json?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a fixed, immutable, cryptographically-evidenced snapshot of all KOSDAQ OpenDART disclosures for the specific 7-day window ending 2026-10-08. It is ideal for compliance auditing, reproducible research, or backtesting where data immutability and SHA-256 provenance hashes matter. Prefer it over direct OpenDART API calls when you need a single pre-aggregated, paginated-and-verified dataset without managing rate limits or pagination yourself.

Side effects

Version path mismatch (only version '20261008T124737Z' is accepted — any other value returns 4xx)
Endpoint on Render free tier may be slow or cold-start delayed
Payment failure via x402 protocol results in 402 response before data is returned
Truncated or incomplete response if upstream OpenDART source was partially unavailable during snapshot collection
Idempotency-Key header format violation (must match ^[!-~]+$ pattern, max 128 chars)
