## 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-news-feed-a922aab3
```

Example prompt: Pull the latest news feed from the BYTE Library x402 gateway — pay per call in USDC from my Base wallet and give me back the signed, provenance-stamped news payload.

## When to prefer this

Choose this endpoint when your AI agent needs tamper-evident, provenance-attested news data and you want to pay per call in USDC without managing API keys — ideal for agents operating in trust-minimized or auditable pipelines where cryptographic proof of data origin matters.

## Known failure modes

- Payment insufficient or not provided — 402 Payment Required returned
- Wallet not configured for Base (eip155:8453) — payment settlement fails
- Feed temporarily unavailable — service error or empty payload
- Malformed x402 payment header — request rejected before processing
- Network congestion on Base causing payment confirmation delay

## How this service works

Verified, provenance-first data feeds for AI agents. Every payload is cryptographically signed and EIP-712 PayloadAttestation provenance-stamped — covering crypto markets, DeFi yields, weather, earthquakes, news, code-pulse, threat-intel, and a slashable fact-oracle. Pay per call in USDC over x402 with no API keys — a wallet, not a secret on the box. Settlement is on Base (eip155:8453). Price is per-feed, derived from expected payload size at $0.005000/KB (floor $0.001000).

## Output

A JSON object containing the 'news-feed' data payload, cryptographically signed and stamped with an EIP-712 PayloadAttestation proving provenance; the response is ~1.27 KB and costs $0.006348 USDC settled on Base (eip155:8453).
