## 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 base-wallet-facts-lookup-09705c22
```

Example prompt: Can you pull up the on-chain facts for the Base wallet 0xEb81d0a682B2116069Cc00A215f618A1074B052b — I want to see its ETH and USDC balances, how many transactions it has sent, and what tokens it holds?

## When to prefer this

Choose this endpoint when you need a quick, structured summary of a Base (chain 8453) wallet's on-chain state — balances, token holdings, transaction history, and account age — without needing to write custom RPC queries. Prefer this over raw RPC calls when you want aggregated data from multiple sources (public RPC + Blockscout) in a single call. Not suitable for other EVM chains (Ethereum mainnet, Polygon, etc.) or for real-time streaming of transactions.

## Known failure modes

- Invalid or malformed address (not a valid 0x + 40 hex char string) returns an error
- Address not found on Base chain 8453 may return zero balances or empty token list
- RPC or Blockscout data source temporarily unavailable may result in partial data
- Rate limiting or payment failure may prevent the call from completing

## How this service works

On-chain facts for any Base address: EOA or contract, first transaction and age, transaction count, ETH and USDC balances, top 10 tokens held with USD value when known, recent contracts created. Information, not investment advice.

## Output

Returns a JSON object with the account type (EOA or contract), ETH and USDC balances, a list of top token holdings with contract addresses and balances, total transaction count, account age in days, first transaction details, contracts created, and the data sources and fetch timestamps used to compile the report.
