## 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 x402-crypto-data-apis-market-overview-7f879305
```

Example prompt: Give me a full crypto market overview right now — show me the top 5 coins with their prices and 24-hour changes, overall market sentiment, and how confident that sentiment reading is.

## When to prefer this

Choose this endpoint when you need a broad, single-call snapshot of the entire crypto market — top assets, 24h performance, and overall sentiment — rather than deep data on a single coin. Ideal for dashboards, daily briefings, or agent workflows that need a quick market pulse before making decisions. The x402 micropayment model means no API key management is needed.

## Known failure modes

- Payment failure: x402 payment not fulfilled or wallet has insufficient USDC balance
- Rate limiting or server overload on the Render-hosted service
- CoinGecko upstream API outage causing stale or missing data
- Invalid format parameter returns malformed or empty response
- Network timeout from the Render free-tier hosting (cold start latency)
