## 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-pulse-spots-149c68b5
```

Example prompt: Can you pull the latest USD spot prices for BTC, ETH, SOL, and HYPE along with their 24-hour changes and give me a quick summary of where the market stands?

## When to prefer this

Use this endpoint when you need lightweight, cheap spot prices and 24h changes for BTC, ETH, SOL, and HYPE only, and do not require Fear & Greed index, funding rates, or DeFi metrics. If you need all of those in a single call, use /v1/pulse instead. At $0.005 USDC per call it is extremely cost-efficient for high-frequency price polling or portfolio dashboards.

## Known failure modes

- CoinGecko upstream outage may cause stale or missing price data
- Rate limiting if the endpoint is called excessively
- Payment failure (x402) if USDC balance is insufficient or payment is not attached
- Network timeout returning no data

## How this service works

Cheap BTC/ETH/SOL/HYPE USD spots + 24h change from CoinGecko, with summary. Use /v1/pulse when you also need Fear & Greed, funding, or DeFi (one call replaces four).

## Output

Returns a JSON object containing: spot prices in USD for BTC, ETH, SOL, and HYPE; 24-hour percentage price changes for each asset; a plain-language summary string describing market conditions; a signals object with additional market context; and a generatedAt timestamp indicating data freshness.
