# Cross-Chain Name Resolver (ENS / Bonfida SNS)

> Cross-Chain Name Resolver (ENS / Bonfida SNS) is a paid API for AI agents from 1c09pdnrx1.execute-api.us-east-1.amazonaws.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Resolves human-readable blockchain names (e.g. vitalik.eth, bonfida.sol) to their underlying wallet addresses across ENS and Bonfida SNS.

## Facts

- Endpoint: GET https://1c09pdnrx1.execute-api.us-east-1.amazonaws.com/v1/resolve/name
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402

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 cross-chain-name-resolver-ens-bonfida-sns-d7fa7b10
```

Example prompt: What wallet address does vitalik.eth resolve to? Also check what address bonfida.sol points to.

## When to prefer this

Use this endpoint when you need to resolve a human-readable blockchain name (ENS .eth or Solana .sol) to a wallet address without setting up direct RPC connections to Ethereum or Solana. Ideal for AI agents that need cross-chain identity resolution in a single API call at minimal cost ($0.001 USDC).

## Known failure modes

- Name not registered or expired — returns null or not-found error
- Unsupported TLD/namespace — name is not ENS or Bonfida SNS
- Malformed name input — missing TLD or invalid characters
- Upstream resolver unavailable — gateway timeout or chain RPC error
- Payment failure — x402 micropayment not accepted

## How this service works

Cross-chain name resolver (ENS, Bonfida SNS) — $0.001 USDC

## Output

Returns the resolved wallet address (and potentially associated metadata) for the given human-readable blockchain name, covering both Ethereum ENS (.eth) and Solana Bonfida SNS (.sol) namespaces.
