## 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 x402-utility-desk-evm-gas-price-feed-5bf08081
```

Example prompt: What are the current gas prices on the Base network right now — give me the base fee, priority fee, and gas price in Gwei?

## When to prefer this

Choose this endpoint when you need real-time EVM gas price data specifically for the Base network and want a simple, low-cost ($0.001 USDC) micropayment-gated REST call rather than running your own RPC node or subscribing to a heavyweight gas oracle. Ideal for agents that need occasional gas checks without managing blockchain infrastructure.

## Known failure modes

- RPC node unavailable — may return 5xx or stale data
- Network congestion causing delayed block data
- x402 payment failure if wallet/facilitator is misconfigured
- Rate limiting if called excessively without payment
- Unsupported network requested — endpoint may only cover Base

## How this service works

Live facts and unblockers for agents: real-time EVM gas prices and a web fetch relay. x402-payable, first call free.

## Output

A JSON object containing the network name ('base'), a UTC timestamp, the current base fee in Gwei, the current gas price in Gwei, the current priority fee in Gwei, and the latest block number. All values reflect real-time on-chain state at the moment of the request.
