## 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 x402-trading-useotto-xyz-80af7d14
```

## When to prefer this

Use this endpoint when you need on-chain transaction or trade history specifically for a Safe (multisig) wallet address, and want paginated results. Prefer this over generic block explorers when you need structured JSON output compatible with Otto AI's DeFi ecosystem and when the account is a Safe smart account on EVM chains.

## Known failure modes

- Missing or invalid userId query parameter returns an error
- Non-EVM address format causes a validation failure
- Empty transactions array returned if the wallet has no history
- Payment not processed (x402) results in 402 Payment Required response
- Rate limiting or upstream Safe data unavailability may cause timeouts

## Output
