## 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-crypto-price-snapshot-usd-c195d2db
```

Example prompt: Can you pull the current spot prices for BTC-USD, ETH-USD, SOL-USD, and DOGE-USD all at once so I can see where the market stands right now?

## When to prefer this

Choose this endpoint when you need real-time USD spot prices for multiple crypto assets in a single low-cost call ($0.001 USDC) with no API key or account setup. It is ideal for agents that need a quick multi-asset price snapshot sourced from Coinbase spot data, especially when you need up to 25 pairs at once. Prefer it over single-asset price lookups when batching is more efficient, and over expensive institutional data feeds when Coinbase spot pricing is sufficient.

## Known failure modes

- Invalid symbol format — malformed trading pair returns error or is counted in 'failed'
- Exceeding 25 symbols returns an error or truncated response
- Unknown or unsupported trading pair symbol results in that pair appearing in the 'failed' count
- Payment not settled via x402 results in 402 Payment Required response before data is returned
- Temporary Coinbase upstream outage may cause elevated failed counts or empty price array
