KR-DART Events — Korean corporate disclosures for AI agents

Real-time DART (Korea's SEC EDGAR equivalent) filing events, structured for machines. Pay per call with USDC via x402 — no account, no API key, no subscription.

Base URL: https://dartapi.ljaysk.com          (machine docs: /llms.txt, /openapi.json)

Korea's exchanges publish ~2,500 corporate filings every trading day, in Korean. This service polls DART every 15 seconds, classifies each filing into 31 machine-readable categories, scores importance 0–1, and serves structured JSON with English labels and English company names.

Related MCP server: OpenDART MCP Server

Quickstart (see the 402)

curl https://dartapi.ljaysk.com/v1/events/material
# -> HTTP 402 with payment requirements (accepts: base / solana)

Python client (pay + fetch in ~60 lines)

See client_example.py. Fund any EVM wallet with a few cents of USDC on Base, then:

X402_PRIVATE_KEY=0x... python client_example.py /v1/events/material

Standard x402 SDKs (x402-fetch, x402-axios, x402 python) work as-is.

MCP server (use from Claude / any MCP client)

mcp_server.py wraps the API as MCP tools (kr_dart_material_events, kr_dart_all_events, kr_dart_company_timeline, kr_dart_filing_detail).

{
  "mcpServers": {
    "kr-dart-events": {
      "command": "uv",
      "args": ["run", "--with", "mcp,eth-account", "python", "/path/to/mcp_server.py"],
      "env": { "X402_PRIVATE_KEY": "0x..." }
    }
  }
}

Typical agent loop

Poll /v1/events/material?since_cursor=<last> every 60s during KST market hours. New filings appear within ~15s of DART publication. Cost ≈ $2/day.
