## 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 crypto-market-overview-4cfb32a2
```

Example prompt: Give me a quick crypto market snapshot — total market cap, 24h volume, Bitcoin dominance, how much it's moved in the last 24 hours, and how far we are from the all-time high.

## When to prefer this

Choose this endpoint when you need a broad, macro-level crypto market snapshot in a single call rather than data on individual coins or pairs. Ideal for dashboards, morning briefings, risk context overlays, or any workflow that needs Bitcoin dominance and ATH distance alongside raw market cap figures. Prefer Crypto Coin Profile or Crypto OHLCV Candles when you need per-asset detail or historical price data.

## Known failure modes

- Data provider outage may return stale or empty values
- Network timeout on the Render.com hosted service under cold-start conditions
- Upstream price feed latency may cause slightly outdated figures during high-volatility periods

## Output

A structured JSON object containing: total crypto market capitalization (USD), 24-hour trading volume (USD), Bitcoin dominance (%), 24-hour percentage change in market cap, and the percentage distance from the all-time high market cap.
