## 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 skills-bankofuniverse-org-e627c4d2 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need a real-time, per-call Bitcoin price feed with micropayment-based access (x402/USDC), especially in agent workflows requiring fresh BTC valuations without a long-term API subscription. Prefer this over batch historical data endpoints when low-latency current price is the priority.

## Known failure modes

- Payment failure (x402 payment not processed or insufficient USDC balance)
- Rate limiting or quota exceeded
- Upstream market data source unavailable, causing stale or missing price
- Network timeout returning no price data
- Invalid or malformed response if BTC symbol is not recognized
