## 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 genexxis-token-price-multi-exchange-median-spot-price-935ce7b5
```

Example prompt: What are the current median spot prices for bitcoin, ethereum, and solana in USD across Binance, Coinbase, Kraken, OKX, and Bybit — including the per-exchange breakdown, 24h change, and cross-venue spread?

## When to prefer this

Choose this endpoint when you need aggregated, multi-exchange median prices rather than a single-exchange feed, especially for arbitrage detection, fair-value estimation, or cross-venue volume analysis. It is superior to single-exchange APIs when cross-venue spread or volume aggregation matters. Supports both CoinGecko IDs and tickers, making it easy to integrate with CoinGecko-based workflows. Covers up to 50 coins per call, ideal for portfolio batch lookups.

## Known failure modes

- Invalid or unrecognized CoinGecko ID or ticker returns an error or omits that coin
- More than 50 IDs submitted may be rejected or truncated
- Unsupported vs currency (e.g. GBP) returns an error or defaults to USD
- If a coin is not listed on a particular exchange, that venue's price is absent
- Network or upstream exchange outages may cause stale or missing data
- 402 Payment Required if x402 payment header is missing or insufficient
