Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need a quick, no-subscription, pay-per-use weather lookup for a named location and are already using the x402 micropayment protocol. Prefer it in agentic contexts where API key management is undesirable and per-call USDC billing is acceptable.

## Known failure modes

- Missing required 'location' field returns a validation error
- Unknown or misspelled location name may return empty data or an error
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response
- Service downtime on Vercel may return 5xx errors

## How this service works

Web scraping and search for AI agents. No auth, no subscriptions. Pay per request in USDC via x402.

## Output

A JSON object with a 'success' boolean and a 'data' object containing weather information for the requested location. The exact weather fields (temperature, conditions, humidity, etc.) are not strictly documented but are nested within 'data'.
