Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 organicryptoyyc-latest-block-by-chain-a2862a19
```

Example prompt: What's the latest block number on Base right now? I need a fresh on-chain snapshot.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call latest block lookup across any of 38 chains (Ethereum, Solana, BSC, peaq, and 34 EVM chains via Pocket Network) without managing your own RPC infrastructure. It is well-suited for agents that need real-time block height checks with USDC micropayment settlement and no subscription setup.

## Known failure modes

- Unsupported chain identifier returns an error or empty response
- RPC node temporarily unreachable causes timeout or 5xx error
- Payment of 0.005 USDC via x402 not provided returns 402 Payment Required
- Malformed chain path parameter returns 400 Bad Request
- Chain may briefly lag if Pocket Network relay is congested

## How this service works

Real-device, multi-region site verification with screenshot proof, live Pocket Network Shannon relay-demand/tokenomics/validator-security data, and on-chain RPC snapshots across 38 chains -- Ethereum, Solana, BSC, and peaq natively, plus 34 more EVM chains via Pocket Network's free public gateway (Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Linea, Scroll, Gnosis, and more) -- 54 metered x402 routes, priced and settled per call in USDC. Migrating to Acurast decentralized cloud compute for censorship-resistant hosting -- stay tuned.

## Output

Returns a JSON object containing the chain identifier (e.g. 'base'), the human-readable chain name (e.g. 'Base'), and the current latest block number (e.g. 20123456) sourced from a live RPC snapshot.
