Coverage:

\n\n

Data Source: Korea Environment Corporation (KECO) via data.go.kr

\n

Verification: Database integrity checked daily against official government sources.

\n

Data Protection: Daily and monthly unique substance limits apply per tier. See response headers (X-Daily-Unique-Used, X-Monthly-Unique-Used) for current usage.

\n

Sandbox: Three substances (Benzene 71-43-2, Ethanol 64-17-5, Formaldehyde 50-00-0) return full data on the free BASIC tier for testing.
