# Solana Validator Lookup

> Solana Validator Lookup is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-14).

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

## Facts

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-lookup-da6b7c6f
```

Example prompt: Can you resolve this Solana validator identity pubkey — say 8abc...XYZ — to its corresponding vote-account address, or 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 when you need to map between Solana validator identity and vote-account pubkeys, or when you need a shortlist of low-risk validator candidates before performing deeper vetting. Prefer it over full validator analysis endpoints when you only need identity resolution or a quick safe-validator shortlist, since it costs less and is faster.

## Known failure modes

- Unknown pubkey — returns empty or 404 if the identity or vote-account doesn't exist on-chain
- Invalid pubkey format — malformed base58 string causes a validation error
- top_n out of range — values below 1 or above 50 are rejected
- Network or RPC unavailability — upstream Solana RPC timeouts cause 503 errors
- Neither vote, identity, nor top_n provided — ambiguous request returns an error

## 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 (vote-account given an identity, or identity given a vote-account) and/or a ranked list of the top-N lowest-risk safe validators with their composite risk scores, ready to feed into deeper vetting workflows.
