# KMDE OpenDART KOSDAQ 7-Day Filings Snapshot

> KMDE OpenDART KOSDAQ 7-Day Filings Snapshot is a paid API for AI agents from kmde-snapshot-candidate.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Returns a versioned, SHA-256-verified snapshot of all KOSDAQ corporate disclosure filings from Korea's OpenDART system over the past 7 days (745 records as of the captured version).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kmde-opendart-kosdaq-7-day-filings-snapshot-7a3b48e0
```

Example prompt: Pull the KOSDAQ OpenDART 7-day filings snapshot for version 20261008T004559Z — I need the full list of all 745 corporate disclosure records with their coverage metadata and SHA-256 page verification hashes.

## When to prefer this

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.

## Known failure modes

- 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
