## 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 etf-holdings-lookup-0ad766d0
```

Example prompt: What are the current holdings of QQQ? I want to see all the stocks and their weights in that ETF.

## When to prefer this

Use this endpoint when you need to programmatically look up the constituent holdings of a specific ETF without requiring an API key or account setup. It's ideal for AI agents that need on-demand ETF composition data paid per-call in USDC via the x402 protocol, especially for popular ETFs like SPY, VOO, QQQ, AGG, XLK, or VTI.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker provided for a non-ETF instrument (e.g. individual stock) may return no data
- Payment failure via x402/USDC results in 402 Payment Required response
- Rate limiting or network timeout if the underlying data source is unavailable
- Delisted or expired ETF ticker returns no holdings data

## How this service works

Top holdings, sector weights, and asset allocation for any US ETF (SPY, VOO, QQQ, AGG, XLK, etc.). Returns up to 25 positions with weights, sector breakdown, and equity/bond/cash split. No API key. $0.018/call.

## Output

A list of securities held within the specified ETF, likely including ticker symbols, company names, weighting percentages, and asset categories that make up the fund's portfolio.
