## 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 dart-impact-analysis-korean-filing-correction-affected-term-lookup-56bfb4ec -d '<json body>'
```

Example prompt: Check DART for any corrections made to 카카오's recent filings — specifically receipt numbers 20260901000456 and 20260901000789 — and tell me which financial terms like 매출액 were changed and what the before and after values were.

## When to prefer this

Use this endpoint when you need to audit or track amendments and corrections to specific DART filings for Korean listed companies — particularly when you have filing receipt numbers (rcept_nos) and want to know exactly which financial terms (e.g. 매출액, 영업이익) changed and by how much. Prefer this over general DART search endpoints when the goal is detecting restatements or verifying the integrity of disclosed figures.

## Known failure modes

- Invalid or unknown corp_code returns empty results or error
- Unrecognized rcept_nos return empty corrections array
- Korean company name not matching DART records causes no results
- Network or payment failure on x402 micropayment layer returns 402 or timeout
- Date filter 'since' in wrong format may return all or no results

## How this service works

Pay-per-call Korean company due diligence, company ID crosswalk, sanctions screening with Korean name variants, Upbit/Bithumb risk events, HWP to Markdown, business status, business-day calendar, address normalisation, law, rates, filings and more. No account or API key: pay each call in USDC on Base via x402.

## Output

Returns a JSON object with two arrays: 'affected' (filings that were impacted but may not have direct corrections) and 'corrections' (an array of objects each containing a rcept_no and a 'changed' array listing financial terms with their before and after values). For example, a correction entry shows the term '매출액' with its original and revised figures.
