## 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-pulse-wallet-intelligence-c5510a18 -d '<json body>'
```

Example prompt: Before I send payment, can you run wallet intel on 0x4f4C15d9bD7c796A9f9B769b78323EA3E0054104 and tell me if it's a real user or a contract, what its ETH and USDC balances are, and whether it's safe to pay?

## When to prefer this

Choose this endpoint when you need rapid on-chain wallet due diligence specifically on the Base network before executing a payment or onboarding a counterparty. It is ideal for x402-based payment flows where you need to verify recipient trustworthiness without requiring API keys or complex integrations. Prefer this over generic block explorer lookups when you need a structured risk score and recommendation rather than raw chain data.

## Known failure modes

- Invalid or malformed address string returns an error or empty metrics
- Address not found on Base (zero activity) may return zeroed metrics with an inconclusive risk score
- Network or RPC timeout from public Base data sources causes delayed or failed response
- Address is a newly deployed contract with no history, leading to low-confidence scoring
- Rate limiting or payment failure via x402 prevents the call from completing

## How this service works

Pay-per-call market intel and data tools for AI agents: trending Base tokens with momentum/risk scores, live token scoring, multi-source spot prices, Base gas tips, wallet intel, x402 merchant reliability checks, DefiLlama TVL, GitHub trending repos, RSS feed digests, and WHOIS domain lookups. Built from free public data — no API keys for callers. USDC via x402 on Base and Solana.

## Output

Returns a JSON object with the queried address, key metrics (transaction count, ETH balance, USDC balance, isContract boolean), a numeric risk score (0–1), and a plain-language recommendation such as 'safe_to_pay' indicating the assessed trustworthiness of the wallet.
