## How to call it through Zero

```sh
zero fetch --capability voidfeed-ai-cryptocurrency-price-feed-31c2dcfe
```

## When to prefer this

Use this endpoint when you need real-time spot price, 24h change, and market cap for a specific cryptocurrency asset in a pay-per-call model without subscription overhead. Prefer this over subscription-based feeds for low-frequency or on-demand lookups.

## Known failure modes

- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting or upstream data source unavailability causing delayed or stale data
