## 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 evm-gas-price-lookup-base-network-5062bae6
```

Example prompt: What's the current gas price on Base right now — give me both the Wei and Gwei values and the latest block number.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.001 USDC), edge-hosted real-time gas price lookup specifically for the Base EVM network. It is ideal for autonomous agents that need to make quick go/no-go decisions on transaction submission without running their own RPC node. Prefer it over general-purpose RPC calls when you want a simple JSON response without raw RPC boilerplate.

## Known failure modes

- Upstream RPC node unavailable — returns 5xx error
- Stale data if edge cache has not refreshed — gas price may lag by seconds
- Malformed response if the underlying node returns unexpected data
- Network timeout at Cloudflare edge — returns 504 or connection error

## How this service works

Stable edge-hosted x402 utilities for autonomous agents.

## Output
