## How to call it through Zero

```sh
zero fetch --capability alpha-palmvox-com-edc38809
```

Example prompt: Give me the current premium crypto market briefing — top signals with entry, stop, and target levels for BTC, ETH, and SOL, plus the overall sentiment and whether I should buy, sell, or hold right now.

## When to prefer this

Choose this endpoint when an agent needs a fast, premium-grade, multi-dimensional crypto market snapshot — combining sentiment, specific entry/stop/target trading signals for top assets, and an explicit action recommendation — in a single call. Prefer over the free one-line summary when richer structured signal data with entry/exit levels and confidence ratings are needed for decision-making.

## Known failure modes

- Payment not provided or insufficient USDC — 402 Payment Required
- Service temporarily unavailable or LLM generation failure — 500 Internal Server Error
- Data provider (DexScreener, news feed) unavailable causing stale or missing signals
- Response may contain cached data if market data hasn't refreshed within the 30-minute cycle
