## How to call it through Zero

```sh
zero fetch --capability solana-latest-block-lookup-39c3385d
```

Example prompt: What's the current slot number on the Solana blockchain right now?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call Solana slot lookup without managing your own RPC infrastructure or an API key subscription. It is particularly useful for agents that only occasionally need Solana block height data and want to settle per-call in USDC via x402 rather than commit to a monthly plan.

## Known failure modes

- Network or RPC outage returns a 5xx error with no slot data
- Payment not settled via x402 returns a 402 Payment Required response
- Solana RPC node lag may return a slightly behind slot number
- Invalid or missing x402 payment header results in rejection

## 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

A JSON object containing the current Solana slot number (e.g. 289456123) and the chain label 'solana', reflecting the live head of the Solana blockchain at the time of the call.
