## 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 synthetic-universe-monthly-weather-data-pack-67348107
```

Example prompt: Fetch me the monthly weather data pack from Synthetic Universe in JSON format — I'll pay the $1.20 USDC via x402.

## When to prefer this

Choose this endpoint when your agent needs monthly weather data and is capable of executing x402 micropayments on Base using USDC. It is purpose-built for agent-to-agent or automated commerce scenarios where human checkout flows are bypassed. Prefer it over traditional weather APIs when you want instant license certificates, pay-per-call pricing at $1.20 USDC, and integration with the x402 micropayment standard rather than API key subscriptions.

## Known failure modes

- Insufficient USDC balance on Base — payment fails, no data returned
- Invalid or missing x402 payment header — 402 Payment Required response
- Unsupported format value (only 'json' is accepted) — schema validation error
- Network or RPC issues on Base blockchain — payment cannot be confirmed
- Endpoint unavailable or rate-limited — 503 or timeout response
