## 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 gpuops-gas-price-lookup-35cce134
```

Example prompt: What's the current gas price on Ethereum right now? I want to know if it's a good time to send a transaction.

## When to prefer this

Use this endpoint when you need real-time gas price data for one of the 7 supported chains and want pay-per-call pricing via USDC on Base (x402 protocol) rather than committing to a subscription. Ideal for agents that only occasionally need gas data or want cost-efficient on-demand lookups.

## Known failure modes

- Unsupported or unrecognized chain name returns an error or empty response
- Payment failure via x402/USDC results in 402 Payment Required response
- Network timeout if the target chain RPC is unresponsive
- Missing chain parameter may return a default chain or an error

## How this service works

Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.

## Output

Returns current gas price data for the requested blockchain chain, likely including gas price in gwei or native fee units, which can be used to estimate transaction costs before submitting on-chain operations.
