## 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 proxy-suverse-io-2bc94a58 -d '<json body>'
```

Example prompt: Pull up the last 20 transactions for Base wallet 0x1234...abcd — I want to see what swaps, transfers, and mints they've done, how much gas they paid, and a plain-English summary of each one.

## When to prefer this

Use this endpoint when you need a quick, parsed, human-readable transaction history for a specific Base chain wallet — ideal for portfolio managers, tax tools, or trading bots that need classified transaction types (swap/transfer/mint/NFT) without parsing raw RPC data. Prefer this over raw Etherscan or RPC calls when you want pre-classified transaction types and one-line summaries out of the box.

## Known failure modes

- Invalid or malformed wallet address returns error
- Wallet has no transactions on Base returns empty list
- Network congestion may delay data freshness
- Rate limiting if called too frequently
- Payment failure via x402 protocol blocks the request
