## 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-experiments-market-snapshot-lab-paidapis-net-2b7f51f0
```

Example prompt: What's the current ETH price in USD and the gas price on Base right now? Also tell me the latest Base block number.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) real-time snapshot of ETH/USD price and Base network gas conditions in a single call. Ideal for agents that need onchain oracle-style data without running their own RPC node or subscribing to a full data provider. Best when you want Base-native data specifically (not Ethereum L1 gas or prices from a CEX).

## Known failure modes

- Payment not provided or invalid — returns HTTP 402 requiring USDC payment on Base mainnet
- Base RPC node temporarily unavailable — stale or missing data
- Invalid referral wallet address format — may cause request rejection or ignored referral
- Network congestion causing delayed block/gas data

## How this service works

Aggregated market snapshot: Ethereum mainnet gas price (Gwei), ETH/USD spot price, and the latest Base mainnet block number and timestamp — combined into one call. Optional ?ref=<address> pays that wallet a 20% referral cut, sent as a separate on-chain transfer after settlement.

## Output

A JSON object containing: the timestamp of the data (dataAsOf), the current ETH/USD price as a number (ethUsdPrice), the current gas price in Gwei (gasPriceGwei), and the latest Base block details including its number (integer) and timestamp (string).
