## How to call it through Zero

```sh
zero fetch --capability defi-signals-market-snapshot-a7f9787e
```

Example prompt: What are the current BTC and ETH prices and is the market greedy or fearful right now? I want a quick snapshot of crypto market conditions.

## When to prefer this

Choose this endpoint when you need a low-cost ($0.002 USDC), single-call market snapshot combining BTC/ETH prices and Fear & Greed sentiment in one response, paid via x402 micropayment on Base — ideal for AI agents that need lightweight, frequent polling without a subscription or API key setup.

## Known failure modes

- 402 Payment Required if x402/USDC payment on Base is not properly attached
- Invalid or malformed payment header causing rejection
- Rate limiting if called too frequently
- Network timeout if defi-signals.org is temporarily unavailable
- Empty or stale data if upstream price feeds are lagging
