## 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 synthora-market-pulse-bfde2265 -d '<json body>'
```

Example prompt: What's the current crypto market pulse for Bitcoin — give me the Fear & Greed Index, BTC dominance, global market cap, and any momentum signals right now.

## When to prefer this

Choose this endpoint when you need a holistic crypto market sentiment snapshot in a single call rather than querying Fear & Greed, market cap, and BTC dominance separately. Ideal for agents that need quick macro-level crypto context without managing multiple API integrations. The pay-per-use x402 model makes it cost-effective for infrequent or on-demand lookups.

## Known failure modes

- Upstream Alternative.me or CoinGecko API outage causes partial or empty result
- Invalid or unrecognized asset name returns no result or generic market data
- Payment failure via x402 USDC on Base results in 402 rejection before data is returned
- Rate limiting or quota exhaustion from underlying data providers causes delayed or failed response

## How this service works

Crypto Fear & Greed Index combined with global market cap, BTC dominance, and momentum signals in a single M2M call. Powered by Alternative.me and CoinGecko. Pay-per-use via x402 USDC on Base.

## Output

A structured object containing the current Fear & Greed Index value and label, global crypto market cap, Bitcoin dominance percentage, and momentum signals — all aggregated from Alternative.me and CoinGecko into a single response payload.
