# Solana Validator Identity/Vote-Account Lookup & Safe Validator Discovery

> Solana Validator Identity/Vote-Account Lookup & Safe Validator Discovery is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Resolves a Solana validator identity pubkey to its vote-account (or reverse), or returns the top-N lowest-risk safe validators by score

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-identity-vote-account-lookup-safe-validator-discovery-9a49b994
```

Example prompt: Can you look up the vote account for the Solana validator with identity pubkey 7K8DVxtNJGnMtUY1CQJT5jcs8sFGSZTDiG7kowvFpECh, and also give me the top 5 lowest-risk safe validators I could stake with?

## When to prefer this

Use this endpoint as a cheap first-step lookup before running deeper validator vetting or risk analysis. Prefer it when you need to resolve a Solana validator identity pubkey to its vote-account (or vice versa), or when you need a shortlist of low-risk staking candidates without paying for a full validator risk report.

## Known failure modes

- Unknown pubkey — provided identity or vote-account does not match any known validator, returns empty or error response
- Invalid pubkey format — malformed base58 string returns a 400-level error
- top_n out of range — value below 1 or above 50 returns a validation error
- No parameters provided — requires at least one of vote, identity, or top_n

## How this service works

Resolve a Solana validator identity pubkey to its vote-account (or the reverse) and optionally get the top-N lowest-risk safe validators by score. Give vote or identity to resolve, or top_n for safe candidates. Cheap first step before validator/vet.

## Output

Returns the resolved counterpart pubkey (identity↔vote-account), and/or a ranked list of up to 50 top-N safest Solana validators with their associated risk scores, suitable for use as input to deeper validator vetting steps.
