## 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 solana-mint-instant-intel-current-slot-block-height-epoch-8152ded5
```

Example prompt: What's the current Solana mainnet slot number and block height right now?

## When to prefer this

Choose this endpoint when you need a fast, cheap (\$0.001 USDC) snapshot of the current Solana chain tip — slot, block height, and epoch — without needing to run your own RPC node or pay for a full RPC subscription. Ideal for agents that need a liveness check or a clock signal at sub-second freshness with minimal cost.

## Known failure modes

- Cache staleness beyond 0.4s during RPC downtime — returned data may be slightly outdated
- Network or upstream RPC errors returning 5xx status
- Payment failure via x402 protocol resulting in 402 Payment Required if USDC not provided
- Endpoint unavailable if the sslip.io host is unreachable

## How this service works

Current Solana mainnet slot, block height and epoch (confirmed commitment, cached <=0.4 s). The cheapest liveness/clock tick for agents.

## Output

Returns a JSON object containing the current Solana mainnet slot (integer), block height (integer), and epoch number (integer), all at confirmed commitment level and sourced from a cache no older than 0.4 seconds.
