## 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`):

Example prompt: Can you query the weather database for current conditions and temperature in Denver, Colorado?

## When to prefer this

Choose this endpoint when you need to query weather data via a flexible natural language or structured query string and are operating in an x402 micropayment-enabled environment on Base. It is well-suited for agents that already handle x402 payment flows and need lightweight, pay-per-call weather database access without a subscription or API key.

## Known failure modes

- Missing or empty query parameter returns validation error
- Ambiguous query string may return empty or irrelevant data
- Micropayment failure (402) if wallet has insufficient USDC balance on Base
- Upstream weather database unavailability causes 5xx errors
- Query too broad or malformed may return generic or null data
