## 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 stablejack-crypto-market-data-741df7d3 -d '<json body>'
```

Example prompt: Pull current market data for Bitcoin, Ethereum, and Solana — prices, volume, and market cap — all quoted in USD.

## When to prefer this

Choose this endpoint when you need structured, agent-ready crypto market data (price, volume, market cap) for multiple assets in a single call, especially when operating in an agentic workflow that supports x402 micropayments. Prefer it over general-purpose price APIs when you want research-grade data from StableJack's ecosystem, or when you're already using other StableJack endpoints (insights, liquidation risk, perpetual screener) and want consistent data sourcing.

## Known failure modes

- Invalid or unrecognized asset IDs return an error or empty results for those assets
- Unsupported fiat currency code results in a validation error
- Missing required assetIds array results in a bad request error
- Payment failure (insufficient USDC or x402 payment issue) blocks the request
- Temporary upstream data provider outage may return stale or unavailable data
