# Solana Validator Cluster Stats

> Solana Validator Cluster Stats is a paid API for AI agents from api.chainmarket-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Retrieves live Solana mainnet validator cluster statistics including top validators by stake, skip rates, commissions, and overall network health metrics.

## Facts

- Endpoint: GET https://api.chainmarket-api.workers.dev/api/crypto/solana-validator-cluster?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-24
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/solana-validator-cluster-stats-ff2cdda8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ouP44jg8oCoIEZMxW8GLO

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 solana-validator-cluster-stats-ff2cdda8
```

Example prompt: Can you pull the top 10 Solana mainnet validators ranked by stake and show me their commission rates, skip rates, and how much of the total stake each one holds?

## When to prefer this

Use this endpoint when you need live, structured Solana validator cluster data without needing a Solana RPC node or API key. Ideal for staking research, network health monitoring, or validator benchmarking. Prefer this over raw RPC calls when you want pre-aggregated metrics (skip rate, stake share, stake-weighted commission) in a single call. Pay-per-use x402 model makes it cost-effective for infrequent queries.

## Known failure modes

- Solana mainnet RPC unavailable — upstream API error returned
- Invalid 'top' parameter value (outside 1-25 range) — likely returns error or default
- Payment failure via x402 — call is not charged if the HTTP 402 response is not fulfilled
- Stale data if RPC is lagging behind the tip of the chain

## How this service works

Solana validator snapshot from the public RPC: active and delinquent validator counts, total active stake in SOL, stake-weighted commission, cluster skip rate over the latest epoch block production, and the top validators by stake with their commission and skip rate.

## Output

Returns a JSON object with: a list of top validators (each with node/vote pubkeys, stake in SOL, stake share %, commission %, leader slots, blocks produced, skip rate), total active validator count, delinquent validator count, total active stake in SOL, cluster-wide skip rate, stake-weighted commission percentage, and the block production slot range used for the query. Data is sourced live from the Solana mainnet RPC.
