## 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 speraxos-wallet-tracker-intel-api-13c4a85b
```

Example prompt: Can you track the on-chain DeFi activity for wallet 0x1234...abcd and tell me what protocols they've been using and their recent transactions?

## When to prefer this

Choose this endpoint when you need AI-summarized DeFi intelligence about a specific wallet address without setting up API keys — particularly useful for pay-per-use agent workflows on Base where you want structured, human-readable insights rather than raw RPC data. Prefer it over generic block explorers when you want interpreted DeFi context (protocol names, position summaries) rather than raw transaction hashes.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or malformed wallet address — returns 400 Bad Request
- Wallet has no on-chain activity — returns empty or minimal result set
- Network or RPC issues causing data unavailability — returns 503
- Rate limiting on underlying data providers — returns 429

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns AI-analyzed on-chain intelligence for the queried wallet, including recent transactions, DeFi protocol interactions, portfolio positions, and activity patterns observed on Base or supported chains. The response is structured intelligence data, not raw blockchain logs.
