## 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 api-web3identity-com-994c302f
```

Example prompt: What's the current price of Cardano (ADA) in USD right now, including how much it has changed in the last 24 hours?

## When to prefer this

Use this endpoint when you specifically need aggregated Cardano (ADA) price data from multiple sources for reliability, and want a simple per-call pay-as-you-go model at $0.01 USDC. Prefer this over exchange-specific APIs when source diversity and Web3-native payment (x402) matter. Best for agents that need real-time ADA pricing without managing API keys.

## Known failure modes

- Token not found or unsupported — likely 404 or empty response
- Payment not provided or insufficient — 402 Payment Required if x402 header is missing
- Aggregator source unavailable — may return stale or null price data
- Rate limit exceeded — 429 Too Many Requests
- Network timeout from underlying price aggregators — 503 or delayed response
