## 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 byte-library-x402-gateway-weather-feed-4dfe7cae
```

Example prompt: Get me the latest weather data from the BYTE Library provenance feed — I need a signed, EIP-712 attested payload and I'll pay in USDC via x402 on Base.

## When to prefer this

Choose this endpoint when you need weather data with cryptographic provenance guarantees (EIP-712 attestation) for trust-sensitive AI agent pipelines, or when you want a walletless, keyless micropayment model (USDC on Base via x402) rather than a traditional API key subscription. Prefer over standard weather APIs when tamper-evidence or on-chain auditability of data provenance is required.

## Known failure modes

- Insufficient USDC balance — payment fails and no data is returned
- Invalid x402 payment header — 402 response with payment requirements
- Feed temporarily unavailable — 503 or empty payload
- Malformed request properties — 400 bad request
- Network congestion on Base causing settlement delay

## How this service works

NWS weather forecasts for 5 US cities (NYC, LA, Chicago, Houston, Miami)

## Output

A JSON payload containing weather data for the requested feed, cryptographically signed and stamped with an EIP-712 PayloadAttestation for provenance verification. Includes the feed name ('weather') and structured weather data. Cost is approximately $0.021485 USDC per call, deducted automatically via x402 micropayment on Base.
