## 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-variable-path-api-a35e78e4
```

Example prompt: Can you fetch the latest EU agri-food price records from DataNexusAI for me?

## When to prefer this

Choose this endpoint when you need programmatic access to specific public datasets (SEBRA payments, PTP road accidents, Hearthstone cards, EU agri-food prices) and are comfortable with per-call USDC micropayments on Base, Polygon, or Arbitrum One. Best suited for agents that need structured open/government data on demand without managing bulk data warehouses.

## Known failure modes

- Invalid or unknown path parameter returns 404 not found
- Insufficient USDC balance causes 402 Payment Required response
- Malformed query parameters may return 400 bad request
- Network or upstream data source outage returns 503
- Rate limiting may return 429 too many requests
