## 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-snapshot-c1e4ee73
```

Example prompt: Give me a full crypto market pulse right now — prices for BTC, ETH, SOL, XRP, and DOGE plus the current Fear & Greed sentiment index and the latest Base block number.

## When to prefer this

Choose this endpoint when you need prices AND sentiment in a single atomic call rather than making separate requests to a price API and a sentiment API. Ideal for trading bots, dashboards, or agents that need a holistic market snapshot at a point in time. Prefer over alternatives when you want no-account, no-API-key access with per-call USDC micropayment settlement on Base via x402. Use the default symbol set (BTC, ETH, SOL, XRP, DOGE) or supply up to 15 custom pairs.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported symbol in the symbols query param — may return partial results or error
- Too many symbols requested (over 15) — returns 400 Bad Request
- Upstream price feed or sentiment index unavailable — may return 503 or incomplete snapshot
- Malformed query string — returns 400 with parameter error

## How this service works

## Output

A JSON object containing: a UTC timestamp of the snapshot, the current Base blockchain network name and block number, a prices block with the count of symbols returned and an array of {symbol, price} pairs, and a sentiment block with the numeric Fear & Greed value (0-100) and its text classification (e.g. 'Greed', 'Fear', 'Extreme Greed').
