## 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 doormat-capital-payverify-statement-5ba5dcfb
```

Example prompt: Pull the last 10 USDC transfer records on Base for wallet address 0xAbc123... and show me the full statement.

## When to prefer this

Choose this endpoint when you need on-chain USDC transfer history for a specific Base wallet address and are willing to pay a small per-call USDC fee via x402. It is purpose-built for Base/USDC activity and supports micropayment-native workflows. Prefer it over generic block explorers when you need a clean API response with no scraping, or when building automated payment-auditing agents that handle x402 payment flows natively.

## Known failure modes

- 402 Payment Required — no payment sent yet; response includes USDC payment address and current amount (introductory ~0.05 USDC)
- Invalid or malformed Base wallet address returns an error or empty transfers array
- Limit parameter out of range or non-integer causes a validation error
- Upstream Base blockchain data unavailable causes a 5xx error
- Payment tx hash not recognized or not yet confirmed returns a payment failure

## How this service works

Base USDC payment-verification tools. /verify is free; /statement is paid, settled in USDC on Base (x402). Pay by sending USDC to the address in the 402 challenge, then retry with header X-PAYMENT-TX: <tx hash>. Introductory pricing through 17 Oct 2026 on /statement (0.15 USDC normally) — see the 402 response for the current amount.

## Output

A JSON object with an 'ok' boolean, the queried address, and an array of USDC transfer records on the Base network. Each transfer entry reflects on-chain transaction data for the specified wallet, paginated by the 'limit' query parameter.
