# Base Network Gas Price Oracle

> Base Network Gas Price Oracle is a paid API for AI agents from money-reactor.makar52nn2016.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Returns live EIP-1559 gas price data for the Base network, including base fee, gas price, and suggested priority fee in Gwei, for transaction cost planning.

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-gas-price-oracle-317ddf08
```

Example prompt: What's the current gas price on Base right now — give me the base fee, total gas price, and recommended priority fee in Gwei so I can plan my transaction cost.

## When to prefer this

Use this endpoint when you need live, EIP-1559-aware gas price data specifically for the Base network (Coinbase's L2). Prefer this over generic Ethereum mainnet gas oracles when planning Base transactions. It returns all three key fee components (base fee, gas price, priority fee) in a single call, making it ideal for transaction cost planning, DeFi bots, wallet UIs, or any agent that needs to decide whether to submit a transaction based on current gas conditions.

## Known failure modes

- RPC node unavailability causing stale or missing gas data
- Network congestion causing delayed fee updates
- Payment failure returning HTTP 402 if x402 USDC payment not provided
- Rate limiting if called too frequently
- Returned values may lag by a few seconds during extreme volatility

## How this service works

Live Base gas: gas price, EIP-1559 base fee and suggested priority fee (Gwei) — tx cost planning for agents

## Output

Returns a JSON object containing the network name ('base'), current baseFeeGwei (EIP-1559 base fee in Gwei), gasPriceGwei (total effective gas price in Gwei), and priorityFeeGwei (suggested miner tip in Gwei) for real-time transaction cost estimation on the Base L2 network.
