# ENS Resolve

> ENS Resolve is a paid API for AI agents from chain.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

## 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 ens-resolve-a297ad84
```

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

## When to prefer this

Use this endpoint when you need to resolve ENS names to Ethereum addresses or reverse-resolve addresses to ENS names, and also want rich profile metadata (avatar, social handles, email) in a single call. Prefer this over raw on-chain ENS calls when you want a managed, paid API without running your own node.

## Known failure modes

- ENS name does not exist or has no resolver set — returns null or error
- Address has no reverse record — reverse resolution returns empty
- ENS name is expired — may return stale or no results
- Network connectivity issues with ENS infrastructure — timeout or 503
- Invalid input format (malformed address or name) — returns 400 or error

## How this service works

Resolve an ENS name to its address and profile records (avatar, url, twitter, github, email, description), or reverse-resolve an address to its primary ENS name. $0.01 per call.

## Output

Returns the resolved Ethereum address for a given ENS name, plus profile records (avatar, URL, Twitter, GitHub, email, description). For reverse lookups, returns the primary ENS name associated with a given address.
