## 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-wallet-sol-domain-reverse-lookup-ac74922e -d '<json body>'
```

Example prompt: What is the primary .sol domain name for the Solana wallet Fw1ETanDZafof7xEULsnq9UY6o71Tpds89tNwPkWLb1v, and does the wallet still own it?

## When to prefer this

Use this endpoint when you need to reverse-resolve a Solana wallet address to its human-readable .sol domain name and simultaneously verify that the wallet still owns that domain on-chain. Prefer this over generic Solana RPC calls when you want a single, clean API that handles the SNS lookup and ownership verification in one step, without needing to write custom on-chain query logic.

## Known failure modes

- Wallet has no favorite .sol domain set — returns null for main_domain and still_owned
- Invalid or malformed base58 wallet address — likely returns an error or empty result
- Wallet previously owned a .sol domain but transferred it — still_owned returns false
- Network or RPC issues reading Solana on-chain data — may return a timeout or error
- Wallet address is valid but has never interacted with Solana Name Service — no domain found
