## 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 b0x402-wallet-profile-evm-wallet-profiling-api-346ea841
```

Example prompt: Can you pull up the on-chain profile for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to know its total transaction count, net worth in USD, and when it first and last appeared on-chain?

## When to prefer this

Use this endpoint when you need a quick, structured on-chain profile for any EVM-compatible wallet address — including net worth, activity age, and transaction volume — and can pay $0.10 USDC per call via the x402 micropayment standard. Prefer this over general blockchain explorers when you need structured JSON output suitable for agent workflows rather than human-readable UIs.

## Known failure modes

- Invalid or malformed wallet address (not matching 0x + 40 hex chars) returns a validation error
- Wallet address has no on-chain history — may return zero values or empty timestamps
- Payment failure via x402 USDC protocol returns 402 Payment Required
- Rate limiting or worker timeout returns 5xx error
- Network or Cloudflare worker unavailability causes request failure
