## 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 money-reactor-market-pulse-live-crypto-prices-sentiment-a66b5689
```

Example prompt: What are the current prices for BTC-USD, ETH-USD, and SOL-USD, and is the crypto market in fear or greed right now?

## When to prefer this

Choose this endpoint when you need a combined snapshot of live crypto spot prices and market sentiment in a single low-cost call, without requiring API keys or account registration. Prefer it over dedicated exchange APIs when you want both price data and a Fear & Greed score together, and when micropayment via x402/USDC on Base is acceptable. It is best for lightweight agent workflows that need a quick market pulse rather than deep order book or historical data.

## Known failure modes

- Invalid or unsupported symbol returns an error or is omitted from the prices array
- More than 15 symbols requested may be rejected or truncated
- Payment failure via x402 returns HTTP 402 with payment details
- Stale data if the hourly refresh has not yet completed
- Network errors from the Cloudflare Worker may return 5xx responses

## How this service works

Full market snapshot in ONE call: batch USD prices (default BTC/ETH/SOL/XRP/DOGE) + Fear & Greed sentiment + latest Base block — one poll replaces three calls for monitoring agents

## Output

A JSON object containing a UTC timestamp, the current Base network block number, an array of spot prices for each requested symbol (up to 15), and a Fear & Greed sentiment score (0-100) with a human-readable classification such as 'Greed' or 'Fear'.
