# Solana .sol Domain Resolver

> Solana .sol Domain Resolver is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Resolves a .sol domain to its current owner wallet address by reading on-chain state, handling both regular and NFT-tokenized domains.

## 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-sol-domain-resolver-7c1a200d -d '<json body>'
```

Example prompt: Who owns the .sol domain bonfida.sol? Look it up on-chain and tell me the wallet address and whether it's tokenized as an NFT.

## When to prefer this

Use this endpoint when you need to resolve a specific .sol domain to its current on-chain owner, especially when NFT-tokenized domains are involved and you need the actual NFT holder rather than just the registry record. Prefer this over off-chain resolvers or cached APIs when accuracy and real-time on-chain state are critical, such as for payment routing, identity verification, or ownership auditing on Solana.

## Known failure modes

- Domain not registered — returns registrado: false with null owner fields
- Invalid .sol domain format — rejected at input validation
- On-chain RPC timeout or Solana network congestion causing lookup failure
- Domain exists in registry but NFT has been transferred and owner mismatch requires special handling
- Payment failure via x402 protocol resulting in 402 response before lookup is attempted

## How this service works

Resolve a Solana Name Service .sol domain to its owner wallet, read directly on-chain (NFT-tokenized domains resolve to the NFT holder).

## Output

Returns the resolved owner wallet address (propietario), the domain string (dominio), whether the domain is registered (registrado), whether it is tokenized as an NFT (tokenizado_como_nft), the on-chain name account address (cuenta_nombre), a Solana explorer link for the domain (explorador), and an optional note (nota) explaining edge cases such as NFT holder vs. registry owner differences.
