Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 booaip-gas-price-api-f3a2bebb
```

Example prompt: What's the current gas price on Base right now in Gwei? I want to know if it's a good time to submit a transaction.

## When to prefer this

Use this endpoint when an AI agent needs live gas price data for the Base blockchain before executing or estimating the cost of an on-chain transaction. Prefer this over general blockchain explorers when you need a simple, machine-readable, pay-per-call API that integrates with the x402 micropayment protocol on Base.

## Known failure modes

- Network congestion causing stale or delayed gas price data
- x402 payment failure due to insufficient USDC balance, resulting in a 402 Payment Required response
- Invalid or unsupported chain parameter returning an error
- Service unavailability on Vercel infrastructure causing 5xx errors

## Output

A JSON object containing the chain name (e.g. 'base') and the current gas price in Gwei (e.g. 0.05), representing the live network gas fee for the Base blockchain.
