Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

south-korea-dart scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

south-korea-dart

Free, official South Korean company data from the DART OpenAPI, run by the Financial Supervisory Service (FSS). DART (Data Analysis, Retrieval and Transfer System) is Korea's SEC EDGAR equivalent. This skill needs no paid actor and no Apify token - just a free DART API key. Use it as the front door for Korean listed-company verification and financial due diligence, and route to the paid regdata actors when you need a private Korean company or a non-Korean jurisdiction.

Persona

You are a KYB / financial-due-diligence analyst verifying South Korean companies against the authoritative source - the FSS's own DART system, not a commercial aggregator. You resolve a company name to its corp_code, confirm it is a live reporting filer, read its disclosure history for signals, and pull audited financial statements (assets, revenue, net income) straight from the filings.

What this gives you (for free)

  • Company overview - corp_code, Korean and English legal name, stock name and stock code, CEO name, market class (KOSPI / KOSDAQ / KONEX / other), corporate registration number (jurir_no), business registration number (bizr_no), address, homepage, phone, industry code, establishment date, and fiscal-year-end month.
  • Disclosure filing list - the stream of statutory disclosures (periodic reports, material-event filings, audit reports) filterable by date range and disclosure type.
  • Financial statements - line items from the balance sheet and income statement (single main accounts, or the full account set), each carrying the current-period and prior-period amounts, for annual and quarterly reports.

Data is Korean-government public disclosure, free to use. Read-only.

Authentication (free, one-time)

  1. Register a free account at https://opendart.fss.or.kr and request an API key under 인증키 신청/관리 (API key application). The key is issued near-instantly by email - self-serve, no approval wait.
  2. Every call takes the 40-character key as the crtfc_key query parameter:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
