## 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 studio-gas-price-lookup-base-ethereum-3ab1c504 -d '<json body>'
```

Example prompt: What's the current gas price on Base right now — give me the base fee and total gas price in Gwei.

## When to prefer this

Use this endpoint when you need a real-time, pay-per-call gas price quote for either the Base L2 or Ethereum mainnet and want a simple HTTP API without setting up your own RPC node. Ideal for AI agents, bots, or serverless functions that need on-demand gas price data without a subscription, with payment settled automatically in USDC via x402.

## Known failure modes

- Invalid chain value (not 'base' or 'ethereum') returns a validation error
- Payment failure via x402 if insufficient USDC balance prevents call completion
- Network or RPC unavailability may cause stale or missing gas data
- Rate limiting if too many calls are made in rapid succession

## How this service works

Studio sells 6 per-call jobs over HTTP, paid in USDC on base via x402 or direct transfer.

## Output

Returns a JSON object with the chain name, chainId, current baseFeeGwei, gasPriceWei, gasPriceGwei, and the timestamp when the data was fetched (fetchedAt). Also includes a status field ('delivered') and the offerId and invoiceId for payment tracking.
