## 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-changes-endpoint-41a2a2b6
```

Example prompt: Pull the EU agri-food import changes for Bulgaria (country code BG) on commodity 1001 from 2020 to 2025, limit to 50 results.

## When to prefer this

Choose this endpoint when you need to retrieve changes in EU agri-food trade metrics — imports, exports, trade balance, or prices — filtered by country, commodity, and date range. It is best suited for time-series analysis of agricultural market data with pagination support, and accepts micropayments via x402 USDC.

## Known failure modes

- Missing required 'input' object returns 400 validation error
- Invalid metric value (not one of price/imports/exports/trade_balance) returns error
- Unsupported country code returns empty result set or 404
- Date range with no available data returns empty array
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Offset beyond available records returns empty result set

## How this service works
