## 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 express-legacy-production-up-railway-app-66a0f1cc
```

Example prompt: Give me a quick daily market briefing in English — I want today's macro snapshot including treasury yields, fed funds rate, and unemployment, plus the top trending crypto coins and BTC's latest price.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.002) daily market snapshot combining both macro and crypto data in one call. Prefer this over the insight tier when you need basic indicators quickly and don't require deep analysis or extended narrative. Use when budget is a constraint or when polling frequently for lightweight monitoring.

## Known failure modes

- FRED data unavailable — fred_available flag returns false, some macro fields may be null
- Upstream RSS feeds unreachable — news section may be empty or stale
- CoinGecko rate limits hit — trending coins or BTC price may be null
- Payment not processed — 402 response if x402 payment header is missing or invalid
- Invalid lang param — request rejected if lang is not 'en' or 'ja'
