## 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 agentfeed-base-gas-price-chain-8453-88f9bc89
```

Example prompt: What's the current gas price on Base — give me both the gwei and wei values along with the base fee and priority fee if available?

## When to prefer this

Choose this endpoint when you need live, dual-unit (gwei + wei) gas price data specifically for Base (chain 8453) with EIP-1559 breakdown (base fee + priority fee) in a single call. Prefer it over generic RPC calls when you need a pre-parsed, agent-ready JSON response without setting up your own node connection. Especially useful for agents automating transactions on Base that need cost estimation without manual unit conversion.

## Known failure modes

- Node unavailable — gas data cannot be fetched from the underlying RPC
- Priority fee or block number may be absent if the node does not supply them (fields omitted or null)
- Stale data if the node is lagging behind the latest block
- Payment failure if x402 micropayment ($0.001 USDC) is not completed correctly

## How this service works

Base gas price (chain 8453) in BOTH gwei and wei, with base fee, priority fee and block number when the node supplies them. Use when you need to answer: What is gas on Base? Both units are returned because a caller asking in wei and a caller asking in gwei are asking the same question. Served from keyless public RPC with three-node fallback, so there is no API key to rotate or expire.

## Output

Returns a JSON object containing: gas_price_gwei, gas_price_wei, base_fee_gwei, base_fee_wei, priority_fee_gwei, priority_fee_wei (when node supplies them), block number, chain name, chain_id (8453), and source identifier. Both gwei and wei units are always returned for each fee component.
