## 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 cryptopulse-market-summary-api-92d90e44
```

Example prompt: Give me a quick crypto market snapshot — current BTC, ETH, and SOL prices with their 24-hour changes, today's Fear and Greed index, and the top 5 trending coins.

## When to prefer this

Choose this endpoint when you need a single consolidated crypto market snapshot in one call rather than querying multiple individual price or sentiment endpoints. It is ideal for agents that need a quick dashboard-style overview of market conditions without the overhead of assembling BTC/ETH/SOL prices, Fear & Greed data, and trending coins from separate sources. Prefer alternatives (like the sibling spot-price endpoint) when you need prices for a broader set of coins or a specific fiat quote currency.

## Known failure modes

- Upstream data provider outage may return stale or empty price data
- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting if called too frequently — may return 429 Too Many Requests
- Network timeout if the aggregation backend is slow — returns 5xx error

## How this service works

One-call market brief: BTC/ETH/SOL prices with 24h change, Fear & Greed index, and top-5 trending coins. Ideal for agents that need a single snapshot.

## Output

A structured JSON snapshot containing current spot prices for BTC, ETH, and SOL with their 24-hour percentage changes, the Crypto Fear & Greed index value and label, and a list of the top 5 trending cryptocurrencies including their names and symbols.
