## 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 macropulse-crypto-pulse-d56f6a20
```

Example prompt: What's the current crypto market pulse — give me BTC, ETH and majors prices along with the Fear and Greed read and whether the macro environment is risk-on or risk-off right now.

## When to prefer this

Use this endpoint when your agent needs crypto market context tied to macro regime signals, not just raw price data. Ideal for multi-asset agents that need to understand whether crypto is in a risk-on or risk-off environment and how it aligns with broader macro flows. Prefer this over generic crypto price APIs when the Fear & Greed read and macro linkage are needed for decision-making.

## Known failure modes

- API unavailable or timeout — service may be temporarily down
- Payment failure — x402 micropayment of $0.05 USDC not processed correctly
- Rate limiting — too many requests in a short window
- Data feed delay — underlying price or sentiment data may be stale during off-hours

## How this service works

Crypto market context for macro and multi-asset agents — BTC, ETH and majors with the Fear and Greed read and the risk-on/risk-off signal that ties crypto to broader macro flows.

## Output

Returns current prices for BTC, ETH, and major cryptocurrencies, the Fear and Greed Index score/label, and a risk-on/risk-off signal that contextualizes crypto within broader macro flows
