# Solana data health

Use this skill to decide whether the Solana verdicts can be relied on right now. Read-only; the free routes need no authentication.

| Need | MCP tool | REST |
|---|---|---|
| Latest finalized slot and its block time | `solana_latest_slot` | `GET /v1/solana/slot/latest` |
| Is Solana data being served right now | `solana_network_health` | `GET /v1/solana/health` |
| Reliability over 1 hour, 24 hours or 7 days | n/a | `GET /v1/solana/health/history` |

- The health status is `up`, `down`, `unknown` or `unavailable` (Solana data not configured). The history has no MCP tool; use REST with `window=1h|24h|7d`.
- Solana responses carry `meta` with `slot` (the finalized context slot of the read), `commitment` (always `finalized`), `as_of`, `age_seconds`, `cache` and `stale`. On the health endpoint `meta.slot` is 0 while no probe sample is stored or Solana data is not configured.

## Payments

The pro routes currently serve free data and no payment is required; paid access via x402 is announced but not active. Details: https://api.criptonlabs.com/docs/guides/payments.md
