## 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 alpha-palmvox-com-e264b4e6
```

Example prompt: Give me a quick crypto market pulse — what's the current sentiment, fear/greed score, top mover, and whether I should be buying, selling, or holding right now.

## When to prefer this

Choose this endpoint when you need the absolute cheapest and fastest single-string crypto market overview — ideal for high-frequency agent polling, lightweight dashboards, or pre-trade context checks where a full analysis ($0.02) is overkill. Prefer over sibling endpoints when you only need a top-level sentiment + action bias without deep token analysis or DeFi yield data.

## Known failure modes

- Stale data if underlying market data feed is delayed or unavailable
- Payment failure if USDC balance is insufficient for the $0.003 x402 charge
- 503/502 if the AI inference or data aggregation backend is temporarily down
- Empty or null summary if market data sources return no signals

## How this service works

One-line market summary — sentiment, top mover, fear/greed, and action bias in a single string. Cheapest market intel on x402 at $0.003. Perfect for agents that need a quick pulse check.

## Output

A structured response with a single-line summary string (e.g. 'NEUTRAL (F&G 50) | SOL -1.8% | Action: HOLD'), plus fields: action (BUY/SELL/HOLD), fearGreed (0-100 number), sentiment (string), topToken (symbol), topChange (percentage string), signalCount, and a link to a free track record URL.
