## How to call it through Zero

```sh
zero fetch --capability vu-velvetdao-xyz-fa677ffa -d '<json body>'
```

Example prompt: What's the current price, market sentiment, and Fear & Greed index for Ethereum — and is the community leaning bullish or bearish right now?

## When to prefer this

Use this endpoint when you need a conversational, AI-synthesized answer to any crypto question — combining real-time price, sentiment, Fear & Greed, and on-chain signals in a single call. Prefer this over raw data APIs when you want a ready-to-display natural language summary rather than structured JSON fields, or when the question is exploratory and spans multiple data dimensions at once.

## Known failure modes

- Unrecognized or very obscure token — may return no data or a vague response
- Network/data feed outage — may return stale or unavailable data
- Malformed or empty question field — likely returns an error or unhelpful response
- Payment failure (x402) — call rejected without valid USDC payment
- Very broad or ambiguous question — response quality may be lower

A natural language answer containing the token's current USD price, recent price change percentages (1h, 24h, 7d), market cap, trading volume, Fear & Greed Index score with label, community bullish/bearish split, and a brief market dominance or trend summary.
