## 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 datanest-forecast-api-via-x402-hub-f8a9a410 -d '<json body>'
```

Example prompt: Can you get me a DataNest forecast for 'global semiconductor demand Q4 2025' — I need the predictive data returned from that query.

## When to prefer this

Use this endpoint when you need forecast or predictive data from the DataNest data provider and are operating in an x402-enabled micropayment environment on Base. It is best suited for agents that can handle on-chain USDC payments per call and need structured forecast outputs without managing a full DataNest subscription.

## Known failure modes

- Invalid or empty query string returns an error or empty data object
- Payment failure via x402 protocol prevents the request from being processed
- Upstream DataNest API unavailable leads to a 502 or error response
- Query too vague or unsupported by DataNest returns null or sparse data
- Rate limiting by the hub or upstream provider results in a 429 error
