# Rooms by Aurmada ENS Resolver

> Rooms by Aurmada ENS Resolver is a paid API for AI agents from rooms.aurmada.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Resolves an ENS name to its Ethereum address (with reverse-check) or an Ethereum address to its primary ENS name, using the ENS Universal Resolver on mainnet including CCIP-Read offchain names.

## Facts

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 rooms-by-aurmada-ens-resolver-856f8939
```

Example prompt: What Ethereum address does vitalik.eth resolve to, and does its reverse record point back to vitalik.eth?

## When to prefer this

Use this endpoint when you need authoritative ENS forward or reverse resolution on Ethereum mainnet, including support for offchain (CCIP-Read/CCIP-Write) names that standard RPC calls miss. Prefer it over generic RPC calls when you want cross-verification (forward + reverse check in one call) or when dealing with subdomains using off-chain resolvers.

## Known failure modes

- ENS name does not exist or has no address record set
- Address has no primary ENS name (reverse record not set)
- ENS name and address do not match on reverse check
- CCIP-Read gateway unreachable or times out for offchain names
- Invalid address format provided (must match 0x hex pattern)
- Network or RPC errors querying Ethereum mainnet

## How this service works

Rooms is one shared space for you, your people, and everyone's AI.

## Output

Returns the resolved Ethereum address for a given ENS name (plus the address's primary ENS name for cross-checking), or returns the primary ENS name for a given 0x address. Includes offchain (CCIP-Read) name resolution via the ENS Universal Resolver on Ethereum mainnet.
