## 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 phantom-api-base-network-latest-block-8ffc01da -d '<json body>'
```

Example prompt: What is the latest block on the Base network right now — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you need low-latency, pay-per-call access to the latest Base (Coinbase L2) block without committing to a subscription RPC provider. Ideal for agents that query block data infrequently or need to avoid managing API keys for infrastructure providers like Alchemy or Infura. Best suited for real-time monitoring, transaction finality checks, or dashboard data pulls on Base specifically.

## Known failure modes

- Network or RPC node unavailability returns a 5xx error
- Payment not received or insufficient USDC returns a 402 Payment Required
- Malformed request body returns a 400 Bad Request
- Base network congestion or reorg may cause stale or inconsistent block data
- Rate limiting or quota exceeded may return 429

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns the latest block object from the Base blockchain, including fields such as block number, block hash, parent hash, timestamp, miner/validator, gas used, gas limit, transaction count, and other standard EVM block metadata.
