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.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
