## How to call it through Zero

```sh
zero fetch --capability base-wallet-profile-lookup-09e068f7
```

Example prompt: Can you pull up the on-chain wallet profile for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — I want to see their ETH balance, USDC balance, transaction count, and whether they're classified as a veteran or a fresh wallet?

## When to prefer this

Use this endpoint when you need a quick, multi-dimensional snapshot of a Base wallet before transacting or interacting with it — especially when you want the activity tier classification (fresh/new/active/veteran) alongside balances in a single call rather than querying multiple RPC endpoints separately. Ideal for pre-flight counterparty checks, airdrop screening, or bot detection workflows on the Base L2 network.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address not found or zero activity may return balances of 0 and tier 'fresh'
- RPC node timeouts on Base may cause delayed or failed responses
- Rate limiting or payment failure (x402) results in 402 Payment Required
- ENS names not supported — must use raw 0x address

## How this service works

On-chain wallet profile on Base: ETH balance, tx count (nonce), USDC balance, activity tier (fresh/new/active/veteran) — pre-flight counterparty check

## Output

A JSON object containing the queried wallet address, the network ('base'), total transaction count (nonce), ETH balance as a decimal, USDC balance, and an activity tier string — one of 'fresh', 'new', 'active', or 'veteran' — indicating how seasoned the wallet is based on its on-chain history.
