Regulatory compliance audit trail
“I need a cryptographically verifiable record of all KOSDAQ company regulatory filings from OpenDART for the week of October 8–14, 2026 — pull the fixed snapshot version 20261014T125307Z with all the SHA256 page hashes for our audit log.”

Technical details
Endpoint
GEThttps://kmde-snapshot-candidate.onrender.com/v1/opendart/kosdaq/20261014T125307Z/all.json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fixed, immutable, cryptographically auditable snapshot of all KOSDAQ OpenDART regulatory filings for the specific 7-day window ending 2026-10-14. It is ideal for compliance auditing, backtesting, or research workflows requiring reproducibility and SHA256 page-level integrity verification. Prefer it over live OpenDART API calls when you need a stable, versioned dataset that won't change across repeated fetches.
Side effects
- Version mismatch — requesting a version string other than '20261014T125307Z' returns an error since the path is fixed to this snapshot
- Service unavailability on Render.com free tier (cold start delays or spin-down)
- Payment failure — insufficient USDC balance or x402 payment not processed, resulting in 402 response
- Idempotency-Key format violation — key outside printable ASCII or exceeding 128 characters causes rejection
- Network timeout if the Render.com instance is cold-starting
