# SameDayDesk Wallet Enricher

> SameDayDesk Wallet Enricher is a paid API for AI agents from x402-url-extractor-production.up.railway.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Given a Base/EVM wallet address, returns a full on-chain profile including account type, ETH and token balances, NFT holdings, proxy detection, activity metrics, and a derived label — no API key required.

## 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 samedaydesk-wallet-enricher-025e2aee
```

Example prompt: Before I send funds, can you pull the full on-chain profile for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know if it's an EOA or contract, what tokens it holds, whether it's a proxy, and what label you'd give it?

## When to prefer this

Choose this endpoint when an agent needs a comprehensive, structured on-chain profile of any Base/EVM address before sending funds, swapping, or calling a contract — especially when no API key is available. It is ideal for pre-transaction due diligence, counterparty profiling, or wallet auditing on Base mainnet without requiring any authentication setup.

## Known failure modes

- Invalid address format (not 0x + 40 hex) returns an error
- Address not found or zero-activity wallet returns sparse profile
- Base mainnet RPC timeout causes delayed or failed response
- Rate limiting from public RPC under high load
- Payment failure via x402 prevents the call from executing

## How this service works

Base address -> agent-ready on-chain profile: EOA or contract, ETH and major-token holdings, token or NFT metadata, EIP-1967 proxy detection, activity, and a derived profile label. Uses public Base mainnet RPC with no account or API key. Useful before an agent sends funds, swaps, or calls a contract.

## Output

Returns a JSON object with: ok (boolean), address (string), type (eoa or contract), native ETH balance, tokenHoldings array with token metadata, holdingsSummary object, contract details (if applicable, including EIP-1967 proxy info), activity object, and a derived human-readable profile label.
