## 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 tokenguard-crypto-market-dominance-api-4050e9a3 -d '<json body>'
```

Example prompt: What's Bitcoin's current market dominance percentage, and how does it compare to Ethereum and the rest of the altcoin market right now?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time cryptocurrency market dominance figures — particularly BTC vs ETH vs altcoin share of total market cap. Prefer this over general market data endpoints when the specific question is about relative market power or dominance ratios rather than absolute prices or volumes. Best for macro crypto market structure analysis.

## Known failure modes

- Empty JSON response if market data is temporarily unavailable
- Rate limiting or payment failure if x402 micropayment of $0.01 USDC is not properly submitted
- 503 errors if the HuggingFace Space is sleeping or under load
- Stale data if upstream market data provider has a delay
- Malformed response if request body parameters are invalid
