## 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 ethereum-wallet-token-tracer-a8d51b83 -d '<json body>'
```

Example prompt: Can you pull a full wallet brief for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to see its ETH balance in USD, any ERC-20 tokens it holds and their value, and who it's been transacting with most?

## When to prefer this

Choose this endpoint when you need a quick, comprehensive on-chain snapshot of an Ethereum wallet — balances, token portfolio, recent activity, and counterparties — without needing an API key or managing RPC infrastructure. Prefer it over raw RPC calls or block explorers when you want spam-filtered, USD-valued token data and counterparty rankings in a single structured response. Best for due diligence, research, or agent-driven wallet monitoring tasks.

## Known failure modes

- Invalid or malformed Ethereum address returns an error without charge
- Address exists but has no token holdings returns empty token list
- Network congestion or RPC errors may cause timeouts
- More than one address in the array is rejected (maxItems: 1)
- Newly created addresses with no history may return minimal data

## How this service works

Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

Returns a wallet brief containing: current ETH balance and its USD equivalent, a spam-filtered list of ERC-20 token holdings with USD valuations, an estimated total portfolio value, a list of recent on-chain transactions and token transfers, and a ranked list of counterparty addresses by interaction frequency or volume.
