## 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`):

## When to prefer this

Choose this endpoint when you need a lightweight, no-account, pay-per-call ENS resolution without setting up any API credentials. Ideal for agents that only occasionally need ENS lookups and want to avoid subscription overhead. The Germany hub location is suitable for European latency needs.

## Known failure modes

- ENS name not registered or does not resolve — may return null address or error
- Invalid ENS name format — returns validation error
- Payment failure via x402 — call not processed
- Network or DNS issues from the Germany hub — transient errors
- Reverse lookup address has no associated ENS name — returns empty or null name

## How this service works
