## 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 xynaptic-crypto-price-e36e8860
```

Example prompt: Can you pull the latest crypto prices for the major coins — BTC, ETH, SOL, ADA, LINK, and DOT — and tell me which ones are up or down the most in the last 24 hours?

## When to prefer this

Choose this endpoint when you need a fast, low-cost, agent-ready snapshot of the six most commonly tracked major crypto assets in USD, especially when you want 24h change and top-mover context in a single call. Prefer it over broader market endpoints when you only need these specific coins and don't need full top-100 data or deep market regime analysis. The $0.01/call price makes it suitable for frequent polling or monitoring workflows.

## Known failure modes

- Upstream price feed unavailable — may return stale or error response
- Network timeout on real-time data fetch — returns 5xx error
- Invalid query parameters — returns 400 bad request
- Payment not provided or insufficient — returns 402 Payment Required
- Asset coverage is fixed to 6 coins; requests for unlisted coins yield no data for those assets
