> Saylor Innovations Data Desk – Solana Validator Rankings is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Returns the top Solana validators ranked by stake, including commission rates, delinquency status, vote credits, stake concentration, median commission, and Nakamoto coefficient summary.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-data-desk-solana-validator-rankings-422b0090
```

Example prompt: Pull me the top 30 Solana validators ranked by stake — I want to see their commission rates, whether any are delinquent, their vote credits, and the overall Nakamoto coefficient for the network.

## When to prefer this

Use this endpoint when you need a pre-ranked, enriched snapshot of the Solana validator set with network-level summary statistics like the Nakamoto coefficient — rather than querying raw Solana RPC nodes yourself. It is especially useful for staking research, decentralization analysis, and validator health monitoring without requiring blockchain RPC infrastructure.

## Known failure modes

- Invalid limit value (outside 1–50 range) may return an error or default result
- Upstream data source outage may return stale or empty validator data
- Payment failure (x402) returns 402 Payment Required before data is served
- Network timeout if the Solana RPC or data aggregator is slow

## How this service works

Solana validator set ranked by stake: commission, delinquency, vote credits, stake concentration, median commission and Nakamoto coefficient.

## Output

A JSON object containing: the chain identifier ('solana'), a summary object with median commission and Nakamoto coefficient, an array of validator objects each with stake, commission rate, delinquency flag, vote credits, and stake concentration metrics, plus data source attribution and a contextual note. The number of validators returned is controlled by the optional `limit` parameter (default 20, max 50).
