## 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-name-service-sol-domain-resolver-cc693648 -d '<json body>'
```

Example prompt: Can you look up who owns the .sol domain bonfida.sol on-chain and give me their wallet address?

## When to prefer this

Choose this endpoint when you need a direct, real-time on-chain resolution of a Solana Name Service .sol domain to its owner wallet — especially when NFT-tokenized domains are involved and you need the current NFT holder rather than a stale cached record. Prefer this over off-chain or cached DNS-style resolvers when accuracy and tamper-resistance matter, such as before sending funds or verifying Web3 identity.

## Known failure modes

- Domain not registered — returns registered: false with null owner
- Invalid .sol domain format provided — validation error
- On-chain RPC timeout or Solana network congestion causing delayed or failed resolution
- Domain exists but has unusual account structure that cannot be resolved
- Payment failure via x402 protocol if USDC balance is insufficient

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

Returns a JSON object with the domain string, the owner's Solana wallet address, whether the domain is registered, whether it is tokenized as an NFT, the on-chain account name, a Solscan explorer link to the owner address, and a note clarifying that this is the account owner (not a payment routing address from domain records).
