# agenttoll.app Basename Resolver

> agenttoll.app Basename Resolver is a paid API for AI agents from agenttoll.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Resolves a Base blockchain name (.base.eth) to its wallet address, or resolves a wallet address to its primary Basename, bidirectionally

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 agenttoll-app-basename-resolver-f5833da6
```

Example prompt: What wallet address does the basename 'yokboyle999' resolve to on Base, and does it have a primary name registered?

## When to prefer this

Use this endpoint when you need bidirectional Basename resolution on the Base blockchain — either to get the wallet address behind a human-readable name, or to find the display name for a wallet address. Prefer this over generic ENS resolvers when specifically working with Base network identities. It handles both directions in a single call, making it ideal for identity verification before payments, display name enrichment, and on-chain identity lookups on Base.

## Known failure modes

- Name not registered or has no resolver — returns null or 404
- Address has no primary Basename set — returns empty or null name
- Invalid input format (neither a valid basename nor 0x address) — returns 400 error
- Network or RPC timeout querying Base chain — returns 5xx error
- Name exists but points to zero address — may return empty result

## How this service works

Basename resolution both ways: name to address, or address to primary name

## Output

Returns the resolved wallet address if given a Basename, or the primary Basename if given a 0x wallet address. Includes the canonical name string and the corresponding on-chain address for the queried identity.
