## 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 heurist-mesh-etf-mutual-fund-snapshot-03e158f0 -d '<json body>'
```

Example prompt: Can you pull up a full snapshot for the SPY ETF — I want to see the expense ratio, top holdings, sector breakdown, and asset allocation?

## When to prefer this

Use this endpoint when you need a quick, structured overview of an ETF or mutual fund including expense ratio, holdings, and sector data. Prefer this over general stock price endpoints when the user is asking about fund-level characteristics rather than individual stock performance or real-time price quotes.

## Known failure modes

- Symbol not found or not an ETF/mutual fund (e.g. passing a stock ticker like AAPL)
- Yahoo Finance data unavailable or delayed for the requested symbol
- Malformed or missing symbol in request body
- Rate limit or payment failure on the x402 protocol

## How this service works
