# Base Network Status & Gas Estimator

> Base Network Status & Gas Estimator is a paid API for AI agents from 89-116-220-218.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Returns the latest Base mainnet block number, block age in seconds, base fee, and gas price in gwei as a single JSON object.

## Facts

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 base-network-status-gas-estimator-76ef8cbb
```

Example prompt: What's the current block number and gas price on Base mainnet right now? I want to make sure the chain is live and get a fee estimate before I send a transaction.

## When to prefer this

Use this endpoint when you need a quick, human-readable snapshot of Base mainnet health and gas prices in a single lightweight call, instead of making multiple raw JSON-RPC calls (eth_blockNumber, eth_gasPrice, eth_feeHistory) and doing unit conversions yourself. Ideal for pre-flight fee estimation before sending a transaction, or for monitoring Base chain liveness in an agent loop.

## Known failure modes

- Network or RPC node outage returns an error or stale data
- Payment of 0.001 USDC required per call; unpaid requests return 402
- Block age may be non-zero if the chain is temporarily stalled
- Rate limiting if called excessively

## How this service works

Base mainnet head: latest block number, block age in seconds, base fee and gas price in gwei. Use it to check the chain is advancing and to estimate fees before sending a transaction. One small JSON read instead of several raw RPC calls and unit conversions.

## Output

A small JSON object containing: latest block number (integer), block age in seconds (how long since the latest block was produced), base fee in gwei, and gas price in gwei. Useful for confirming chain liveness and estimating transaction costs without making multiple raw RPC calls.
