## 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-filing-change-events-by-corp-code-7efc695c
```

Example prompt: Pull all the DART filing change events for Korean company corp_code 00126380 — I want to see what terms were amended and what the before and after values were, going back to 2025-01-01.

## When to prefer this

Use this endpoint when you need to specifically track amendments and revisions to Korean DART financial disclosures for a known company (by corp_code), especially when auditing restatements, monitoring regulatory corrections, or building compliance workflows around Korean listed companies. It is preferable over general DART filing retrieval when the focus is on what changed rather than what was originally filed.

## Known failure modes

- Missing or invalid corp_code returns an error or empty result
- corp_code not found in DART returns empty changes array
- Payment failure (402) if USDC on Base is not provided or insufficient
- since date in wrong format may return unexpected results or error
- Rate limiting or temporary DART API unavailability upstream

## 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 containing the corp_code queried and an array of change events, each with a receipt number (rcept_no), a reference to the original filing, and an array of term-level diffs showing the term name (in Korean), the value before the amendment, and the value after the amendment.
