## 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 crypto-spot-price-with-24h-change-d66af182
```

Example prompt: What is the current spot price of ETH in USD and how much has it changed in the last 24 hours?

## When to prefer this

Choose this endpoint when you need both the current USD price AND the 24-hour change for a crypto asset in a single call. It is especially useful for quick market snapshots, portfolio checks, or price alert evaluations. Prefer it over raw on-chain price feeds when you want aggregated market pricing rather than a specific DEX quote. The sibling endpoint on this service provides only spot price without the 24h delta if that delta is not needed.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty result
- CoinGecko data source temporarily unavailable causes stale or missing data
- Malformed symbol parameter (e.g. extra spaces or wrong casing) may result in no match
- Rate limiting or payment failure returns a 402 response
