## How to call it through Zero

```sh
zero fetch --capability solana-slot-height-lookup-4f95ae63
```

Example prompt: What is the current slot height on the Solana blockchain right now?

## When to prefer this

Choose this endpoint when you need a real-time, no-signup, pay-per-call lookup of Solana's current slot height without managing API keys. Ideal for AI agents that need occasional Solana chain data on demand and want to pay micropayments via USDC on Base rather than maintain subscriptions. Prefer over free RPC endpoints when deterministic, metered access is needed.

## Known failure modes

- Solana RPC node unavailable — returns error or non-ok response
- Payment verification failure — x402 payment not accepted, endpoint returns 402
- Invalid schema parameter — may return validation error
- Network congestion causing stale slot data

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'paid' boolean confirming the x402 micropayment was processed, and the current Solana slot height (block index) representing the number of slots that have elapsed since genesis on the Solana network.
