Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tradepulse-us-trade-flow-tariff-signal-e995a0ee
```

Example prompt: Pull the latest US trade signal for steel — I want to see monthly import and export volumes, year-over-year trend, which countries we're most dependent on, and what the tariff situation looks like.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call macro trade signal for a specific commodity — especially for gauging US supply chain dependence, tracking reshoring/decoupling trends, or assessing tariff burden by sector. Prefer this over general economic APIs when you need both trade flow data and tariff classification in a single call for common commodity categories like steel, electronics, vehicles, pharma, chemicals, oil, or grain.

## Known failure modes

- Unknown or unsupported commodity category returns no data or error
- Payment not processed (x402 payment required — 0.05 USDC on Base)
- Data lag: US Census data may be 1-2 months behind current date
- Ambiguous category string may match wrong commodity bucket
- Rate limiting or service unavailability for the hosted endpoint

## How this service works

US trade-flow + tariff signal by commodity

## Output

Returns a structured trade signal for the requested commodity including: latest monthly US import and export dollar values, year-over-year percentage change for both, the top-5 source countries with their import share percentages and a single-country concentration metric, and the US tariff profile for that category (duty-free share vs dutiable rate range).
