## 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 deepsearch-krx-etf-context-api-8c3ff0f8
```

Example prompt: Can you pull up the holdings and issuer info for the KRX ETF with code 305720 — I want to see which stocks it holds?

## When to prefer this

Use this endpoint when you need structured ETF holdings and issuer metadata for a specific KRX-listed ETF identified by its 6-digit code, particularly in pay-as-you-go agent workflows without subscription overhead. Prefer it over general market data APIs when you need KRX-specific ETF composition data with no monthly commitment.

## Known failure modes

- Invalid or non-existent 6-digit KRX ETF code returns empty or error response
- Payment failure on Base Mainnet if USDC balance is insufficient or x402 wallet not configured
- ETF code for a regular stock (not ETF) may return no data
- Rate limiting or network timeout from the pay-per-query infrastructure
- Stale holdings data if ETF rebalancing has not yet propagated

## How this service works

Up to 10 years of financials + 3 years of daily price history for all 2,000+ KRX stocks. Pay-per-query with USDC on Base Mainnet — no subscription.

## Output

Returns a JSON object with the ETF's Korean name, issuer (asset management company), ticker symbol, and a list of constituent holdings each with stock name and symbol.
