## 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

```

Example prompt: What is the latest block number and timestamp on the Solana blockchain right now?

## When to prefer this

Use this endpoint when you need a quick, lightweight lookup of the current Solana chain tip without setting up your own RPC node. Ideal for agents that need to anchor timestamps, confirm network liveness, or track block progression without running Solana infrastructure.

## Known failure modes

- Solana RPC node temporarily unavailable — returns 5xx error
- Payment not provided or insufficient — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Network congestion causing stale data

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns the latest block number (block height) and the timestamp of the most recently produced block on the Solana blockchain, useful for confirming chain liveness and anchoring time-sensitive operations.
