## How to call it through Zero

```sh
zero fetch --capability api-web3identity-com-1c0b1b99
```

Example prompt: What is the current price of Bitcoin right now, including the 24-hour change?

## When to prefer this

Use this endpoint when you need the current Bitcoin price aggregated from multiple sources for reliability, especially in web3-native or DeFi contexts where x402 micropayment access is acceptable. Prefer over single-source price feeds when accuracy through aggregation matters.

## Known failure modes

- Token not found or unsupported — likely returns 404 or empty result
- Aggregated price sources temporarily unavailable — may return stale or partial data
- Payment of $0.01 USDC not fulfilled — returns 402 Payment Required
- Rate limiting exceeded — returns 429 Too Many Requests
