# 402.com.tr

402.com.tr is a narrow, single-purpose host serving agents that need a one-shot portfolio snapshot of a Base chain wallet. It targets use cases where an agent must quickly assess the composition and USD value of a wallet's holdings without requiring streaming data or multi-chain support.

## When to use this host

Use this host when an agent needs a single-shot, read-only portfolio snapshot for a Base (eip155:8453) wallet address. It is not suitable for wallets on any other EVM chain (e.g., Ethereum mainnet, Polygon, Arbitrum). Do not use it for real-time or streaming price feeds, historical portfolio data, transaction history, or any write operations such as transfers or swaps. For multi-chain portfolio coverage, look for hosts that explicitly support additional EVM networks. For streaming price data, use a dedicated price-feed host.

## Capabilities

### Wallet Portfolio Snapshot

Retrieves the full ERC-20 and ETH holdings of a Base wallet address, including aggregate USD value and per-token balances with live pricing.

- **`fetch-wallet-portfolio`** — Returns a complete ERC-20 token portfolio for a Base wallet address, including ETH balance, token count, total USD value, and per-token holdings with live USD prices.

## Skill reference

### `fetch-wallet-portfolio`

*Not for:* Do not use for non-Base (eip155:8453) addresses or for streaming/real-time price feeds; this is a single-shot portfolio snapshot. Not suitable for EVM chains other than Base.
