## 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 binance-spot-price-api-oussapi-duckdns-org-09390a63
```

Example prompt: What's the current Binance spot price for ETH right now?

## When to prefer this

Use this endpoint when you need a single real-time Binance spot price for one cryptocurrency symbol and want a simple, low-cost per-call REST API. Prefer the sibling batch endpoint if you need prices for multiple symbols at once. Use this over generic market data APIs when you specifically need Binance-sourced spot pricing.

## Known failure modes

- Unsupported or invalid symbol returns an error (e.g. 'DOGE' may or may not be supported — check supported symbols list)
- Network or DNS errors due to DuckDNS dynamic hostname
- Payment required (x402) if USDC micropayment not included or fails
- Rate limiting or downtime on the underlying Binance API feed

## How this service works

## Output
