## 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 orchard-data-market-brief-967259b6
```

Example prompt: Give me a quick market brief — I want current crypto prices like BTC, major US ETF prices like SPY, and the crypto fear and greed index.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.005) per-call market snapshot covering both crypto and US ETFs plus sentiment index, especially in agentic workflows where pay-per-use micropayments via x402/USDC on Base are acceptable and no long-term API subscription is desired.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 requiring x402 payment
- Rate limit or worker capacity exceeded — returns 5xx error
- Market data source unavailable — may return stale or partial data
- Malformed request — returns 4xx error
