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 datanexusai-trade-openness-analytics-4dc47e8f
```

Example prompt: What is the trade openness index for Germany — I need the trade-to-GDP ratio showing how exposed its economy is to international imports and exports.

## When to prefer this

Choose this endpoint when you need a quick, per-country trade openness metric (trade-to-GDP ratio) and are willing to pay a $0.01 USDC micropayment. Ideal for agents performing country-level economic benchmarking, market entry analysis, or macroeconomic research. Prefer this over general web search when you need structured, machine-readable trade analytics that can be directly fed into downstream computations.

## Known failure modes

- Invalid or unrecognized country code returns a 404 or error response
- Unsupported country code format (e.g. wrong ISO standard) may yield no results
- Insufficient USDC balance or missing x402 payment header results in 402 Payment Required
- Rate limiting or network errors may cause intermittent failures
- Data may be unavailable for very small or non-reporting economies

## How this service works

Public data API for SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices, and trade/market analytics. Paid data endpoints use x402 (USDC micropayments). Docs and discovery endpoints are free.

Machine-readable discovery: `https://api.datanexusai.org/openapi.json`, `https://api.datanexusai.org/llms.txt`, `https://api.datanexusai.org/.well-known/x402`.

Human docs: `/docs` and `/api/`.

## Output

Returns trade openness analytics for the requested country, typically including the trade openness index (sum of imports and exports as a percentage of GDP), and possibly historical trend data or component breakdowns (import share, export share) for the specified country code.
