## 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 x402-chain-intel-base-gas-price-7dd99c81 -d '<json body>'
```

Example prompt: What are the current gas prices on the Base blockchain right now? I need the latest fee data before I send a transaction from my trading bot.

## When to prefer this

Choose this endpoint when you need real-time gas price data specifically for the Base network and are already operating within the x402 micropayment ecosystem. It is well-suited for trading bots, arbitrage engines, or DeFi automation that needs low-latency on-chain fee intelligence before submitting transactions. Prefer it over generic RPC calls if you want a pay-per-use model without managing your own node infrastructure.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required response
- Base RPC node unavailable or slow — timeout or 503 error
- Invalid or missing authentication/payment header — 401 or 400 error
- Stale data if upstream Base node is lagging — returned values may not reflect the latest block
- Rate limiting if too many calls in a short window — 429 Too Many Requests
