## 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 agentbit-crypto-market-sentiment-d82d6453 -d '<json body>'
```

Example prompt: What's the current crypto market sentiment — give me the Fear & Greed index score and classification, along with the total market cap, 24h volume, and BTC and ETH dominance right now.

## When to prefer this

Choose this endpoint when you need a quick, combined snapshot of both macro crypto market sentiment (Fear & Greed index) and global market statistics in a single pay-per-call request — ideal for agents that need sentiment context without managing API keys or subscriptions. Best when you need both sentiment and market cap/dominance data together rather than from separate sources.

## Known failure modes

- Upstream data provider unavailable — may return 5xx error
- Empty response body if data source has no current reading
- Payment not accepted — 402 response if x402 payment header is missing or invalid
- Rate limiting if called too frequently without valid payment

## How this service works

Crypto market sentiment in one call: the Fear & Greed index (0-100 with classification) plus global market stats — total market cap, 24h volume, BTC/ETH dominance and 24h change. Free public data, $0.002.

## Output

A JSON response containing the Fear & Greed index value (0-100) with a textual classification (e.g. 'Extreme Fear', 'Greed'), plus global crypto market statistics including total market capitalization, 24-hour trading volume, Bitcoin dominance percentage, Ethereum dominance percentage, and 24-hour market cap change.
