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 ishob-ens-basename-resolver-735ca983
```

Example prompt: What Ethereum address does vitalik.eth resolve to, and can you also grab any profile records like avatar, Twitter, and GitHub linked to that name?

## When to prefer this

Use this endpoint when you need authoritative, bidirectional ENS and Basename resolution in a single call, including profile records and primary name verification. Prefer it over DIY on-chain calls when you need social profile metadata (avatar, Twitter, GitHub, etc.) alongside address resolution, or when working with Base L2 Basenames as well as standard .eth names. The pay-per-call model (no subscription) makes it cost-effective for sporadic or agent-driven lookups. 404s are free, so speculative resolution is safe.

## Known failure modes

- 404 returned when name does not exist or address has no primary name — no charge incurred
- Invalid address format (not a valid 0x Ethereum address) may return an error
- Offchain / CCIP-Read names may have slower resolution or intermittent availability depending on the offchain gateway
- Providing both name and address simultaneously may cause ambiguity — use one or the other
- Non-ASCII or punycode names may need to be pre-normalized before submission

## How this service works

Resolve ENS names and Basenames both ways. name -> Ethereum address, Base address and profile records (avatar, description, url, email, Twitter/X, GitHub, Discord, Telegram) and whether it is that address's primary name; address -> its primary ENS name and primary Basename, each verified to resolve back to the same address. Works for .eth, *.base.eth, subnames and offchain (CCIP-Read) names. Unknown name or address = 404, not charged.

## Output

For a name lookup: the resolved Ethereum address, Base address, whether it is the primary name for that address, and available profile records (avatar, description, URL, email, Twitter/X, GitHub, Discord, Telegram). For an address lookup: the primary ENS name and primary Basename, each verified to resolve back to the same address. Returns 404 (not charged) if the name or address is unknown.
