## 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 the-stall-ethereum-block-number-lookup-edffe682
```

Example prompt: What is the current Ethereum block number right now? Pay with USDC on Base — no API key needed.

## When to prefer this

Choose this endpoint when you need the current Ethereum block number without setting up accounts or API keys, and are comfortable paying micro-amounts of USDC per call via x402 on Base mainnet. Ideal for AI agents needing on-chain time references, block confirmations, or chain state checks in a permissionless, pay-per-use model.

## Known failure modes

- Node or RPC unavailability returns 5xx error
- Payment rejected or insufficient USDC balance returns 402
- Malformed request returns 400 with schema validation error
- Chain congestion or reorg may cause briefly stale block number

## How this service works

Returns an Ethereum block header and transaction hashes by block number, hex string, or tag (latest/pending/earliest/safe/finalized). Fields: block_number, hash, parent_hash, miner, timestamp_iso, gas_used, gas_limit, base_fee_gwei (EIP-1559), tx_count, transaction_hashes. Supports Ethereum (default), Base, Polygon, and Arbitrum. $0.002/call — 33% below comparable market rate.

## Output

Returns the current Ethereum block number (latest block height), reflecting the most recently mined block on the chain at time of call.
