## 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 money-reactor-multi-asset-usd-price-snapshot-47b0c763
```

Example prompt: Can you pull the current USD spot prices for BTC, ETH, SOL, and AVAX all at once? I need the latest Coinbase spot prices for those four pairs.

## When to prefer this

Choose this endpoint when you need current USD spot prices for multiple cryptocurrencies in a single API call without requiring an account or API key — ideal for agents that need pay-per-call pricing, on-chain settlement via x402, and batch price lookups (up to 25 pairs) sourced from Coinbase spot markets.

## Known failure modes

- Invalid symbol format returns error or increments failed count
- Requesting more than 25 symbols may be rejected or truncated
- Payment failure via x402 results in 402 response before data is returned
- Unsupported or delisted trading pairs increment the failed counter
- Network timeout on Coinbase upstream returns partial or empty results
