## 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 kronos-signals-macro-context-api-f6e5a36c
```

Example prompt: What are the current macro conditions — VIX fear gauge, US dollar index, 10-year yield, S&P 500, and gold price — so I can assess the TradFi backdrop for my crypto trades?

## When to prefer this

Use this endpoint when you need a quick, low-cost snapshot of traditional finance macro indicators (VIX, DXY, yields, equities, gold) to provide market context for crypto trading decisions. Prefer this over building your own multi-source aggregation since it combines stooq and Yahoo Finance with null-safe, never-fabricated responses. Ideal for agents that need to correlate crypto market behavior with TradFi risk sentiment.

## Known failure modes

- All fields return null when both stooq.com and Yahoo Finance are unreachable
- Stale data (up to 15 minutes old) returned due to caching layer
- Payment failure if 0.001 USDC x402 payment is not included or is malformed
- HTTP 402 if no payment header is present

## How this service works

TradFi macro context for crypto traders and agents: VIX (fear gauge), DXY (US Dollar Index), US 10-Year yield, S&P 500 (SPX), and gold. Sourced from stooq.com and Yahoo Finance in parallel with 15-minute caching. All fields are null if sources are unreachable — never fabricated. $0.02 USDC via x402.

## Output

A JSON object containing the latest values for VIX, DXY (US Dollar Index), US 10-Year Treasury yield, S&P 500 (SPX), and gold price. All fields are null if upstream sources (stooq.com and Yahoo Finance) are unreachable — values are never fabricated. Data is cached for up to 15 minutes.
