## 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-summary-4cd4b3d8 -d '<json body>'
```

Example prompt: Can you give me a plain-English summary of the Base wallet at 0x4838B106FCe9647Bdf1E7877BF73cE8B0BAD5f97 — what type of address is it, what does it hold, and are there any warnings I should know about?

## When to prefer this

Choose this endpoint when you need a quick, human-readable profile of a Base address combining onchain data (ETH balance, token holdings, nonce, contract detection) with an AI-generated classification and plain-English summary. Prefer it over raw RPC calls when you want a structured label and narrative rather than raw blockchain data, and when Base mainnet is the specific network of interest.

## Known failure modes

- Invalid address format (not 0x + 40 hex) returns an error
- Address not found or unrecognized on Base mainnet
- RPC or onchain read failures causing incomplete data
- Payment not received or x402 protocol failure preventing the call
- AI model unavailability causing summary generation failure

## How this service works

Plain-English profile of one Base address. JSON body: address (0x + 40 hex). Reads it onchain (contract or wallet, nonce, ETH balance, balances of common tokens), then an AI model returns a 2-4 sentence summary, a profile (new_or_empty, active_wallet, contract, high_value, unknown), key points and warnings. The raw reads are included. Does not identify owners. Not financial advice. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

## Output

Returns a JSON object containing: a 2-4 sentence plain-English summary, a profile label (new_or_empty, active_wallet, contract, high_value, or unknown), an array of key points, an array of warnings, and the raw onchain reads (ETH balance, token balances, nonce, contract detection). Does not identify real-world owners. AI-generated; not financial advice.
