# Wallet Activity Overview

> Wallet Activity Overview is a paid API for AI agents from www.x402financialdata.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-17).

Returns a comprehensive Ethereum wallet profile in one call: ETH balance, transaction count, contract vs. EOA detection, first/last transaction timestamps, and computed wallet age.

## 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 wallet-activity-overview-1b165597
```

Example prompt: Give me a full wallet overview for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to know the ETH balance, total transaction count, whether it's a contract or regular wallet, and how old the wallet is based on its first and last transaction.

## When to prefer this

Choose this endpoint when you need a holistic snapshot of an Ethereum wallet in a single API call rather than stitching together balance, nonce, code, and transaction history queries separately. It is ideal for KYC/onboarding checks, airdrop eligibility screening, fraud detection, or any workflow that needs to characterize a wallet's age, type, and activity level at once. Prefer it over individual /wallet-balance or /transaction-count endpoints when you need multiple data points simultaneously to reduce latency and cost.

## Known failure modes

- Invalid or malformed Ethereum address returns a 400 or error response
- Address with zero transaction history may return null for first/last transaction timestamps
- Only Ethereum mainnet ('eth') is supported; other chains return an error
- Network timeouts or Etherscan API rate limits may cause intermittent failures
- Newly created contracts with no transactions may have partial data

## How this service works

Wallet activity overview for an Ethereum address in one call: native ETH balance, transaction count, contract-vs-EOA detection, and first/last transaction activity with computed wallet age -- from Etherscan's V2 API. Bundles 5 separate lookups (balance, nonce, eth_getCode, earliest tx, latest tx) that a caller would otherwise have to stitch together from /wallet-balance, /transaction-count, and two /wallet-transactions calls. $0.02/call.

## Output

A JSON object containing the wallet's native ETH balance, total outbound transaction count (nonce), a boolean or label indicating whether the address is a smart contract or externally owned account (EOA), the timestamp of the first transaction, the timestamp of the most recent transaction, and the computed wallet age derived from those timestamps.
