## 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 vietnam-holiday-api-generic-crypto-quote-yahoo-finance-2e28ac79
```

Example prompt: What's the current price of Solana? Look up the SOL-USD quote for me.

## When to prefer this

Use this endpoint when you need a quick, low-cost delayed crypto price quote for any Yahoo Finance-supported cryptocurrency pair beyond just BTC. Prefer the sibling BTC-USD endpoint for Bitcoin specifically. This endpoint is ideal for altcoins (ETH, SOL, DOGE, ADA, XRP, LTC, etc.) where you need broad symbol coverage without maintaining a full exchange connection.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty result
- Yahoo Finance data outage may cause failed or stale responses
- Symbol must be in Yahoo Finance format (e.g. ETH-USD, not just ETH) — incorrectly formatted symbols will fail
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Generic crypto quote via Yahoo Finance. Pass ?symbol=SYMBOL-USD (e.g. ETH-USD, SOL-USD).

## Output

Returns a delayed market quote for the requested cryptocurrency pair, including price data sourced from Yahoo Finance (e.g. current/last price, possibly bid/ask, volume, and timestamp metadata depending on Yahoo Finance response).
