## How to call it through Zero

```sh
zero fetch --capability oblique-markets-base-gas-price-feed-daca9572
```

Example prompt: What's the current gas price on Base mainnet right now — give me both the wei and gwei values including the EIP-1559 baseFeePerGas from the latest block?

## When to prefer this

Choose this endpoint when you need real-time Base mainnet gas prices with EIP-1559 baseFeePerGas specifically — ideal for agents that need to decide whether to submit a transaction, estimate fees, or monitor gas trends on Base L2. Prefer over generic Ethereum gas oracles when Base-specific data is required.

## Known failure modes

- RPC node unavailability causing stale or missing data
- Network congestion leading to delayed block data
- Rate limiting if called too frequently
- HTTP 402 payment required if x402 payment header not included or USDC balance insufficient

## How this service works

Use when an agent needs base gas price. Returns Current Base gas price: fetch EIP-1559 latest-block base fee and gas price in wei and gwei from redundant public RPCs, with block freshness metadata for transaction planning. $0.002.

## Output

Returns the current Base mainnet gas price and the latest block's baseFeePerGas in two units: wei (raw integer) and gwei (human-readable decimal), sourced from redundant public RPC nodes for reliability.
