## 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-markets-changes-api-6575bb4e
```

Example prompt: Show me EU agri-food commodity price changes of at least 15% for Bulgaria and Romania, focusing on wheat (commodity code 1001), and return the top 20 results.

## When to prefer this

Use this endpoint when you need to detect significant price movements in EU agricultural and food commodity markets, filtered by specific countries or commodity codes. It is ideal for market monitoring, alerting workflows, and commodity analytics that require threshold-based filtering. Prefer this over generic trade data endpoints when your focus is specifically on percentage-change signals in EU agri-food markets.

## Known failure modes

- Invalid or unsupported country code returns empty results or a 400 error
- Invalid commodity code format causes a 400 bad request
- Payment not included or insufficient USDC (x402) results in a 402 Payment Required response
- Offset beyond available data returns an empty result set
- Very high min_percent threshold returns no matching records

## 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.

## Output

A paginated list of EU agri-food commodity price changes, each record identifying the commodity, country, and percent change, filtered to movements above the specified minimum threshold. Results can be scoped by country codes and commodity codes.
