## 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 402-com-tr-base-chain-status-c15ccb65
```

Example prompt: What are the current gas fees on Base right now — give me the base fee, priority fee in Gwei, today's ETH price, and what a simple ETH transfer would cost me in dollars?

## When to prefer this

Use this endpoint when an AI agent needs to assess real-time Base chain conditions before timing or budgeting a transaction — particularly when you need the combined view of block height, gas fees (base + priority), ETH spot price, and transfer cost estimate in a single call rather than querying multiple RPC endpoints separately.

## Known failure modes

- Upstream Base RPC or price feed unavailable — may return 5xx or stale data
- Network congestion causing delayed chain data
- Payment of $0.005 USDC not provided or invalid — returns 402 Payment Required
- Rate limiting if too many requests in a short window

## How this service works

Live Base chain snapshot: latest block, base fee + priority fee (Gwei), current ETH price, and the estimated USD cost of a simple ETH transfer. For agents timing or budgeting transactions.

## Output

Returns a JSON snapshot of the Base chain including: latest block number, current base fee in Gwei, current priority fee in Gwei, live ETH price in USD, and the estimated USD cost of a standard ETH transfer at current network conditions.
