## 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 vextorium-tezos-account-lookup-a58ef5eb -d '<json body>'
```

Example prompt: Can you pull up the full account details for Tezos address tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb — I want to see the XTZ balance, any staked amount, which baker it's delegated to, FA token holdings, and its USD value?

## When to prefer this

Use this endpoint when you need a comprehensive Tezos account profile in a single call — covering balance, staking, delegation, token holdings, activity history, and USD valuation. Prefer it over block explorers when you need machine-readable structured data for tz1/tz2/tz3 user accounts or KT1 contract accounts. Best suited for portfolio dashboards, account audits, DeFi analytics, and any agent workflow requiring Tezos on-chain state.

## Known failure modes

- Invalid or malformed Tezos address returns an error or empty result
- Address that has never been active may return null activity timestamps
- Upstream TzKT or DefiLlama outage may cause stale or missing data
- KT1 smart contract addresses may have limited delegation data (delegated: null)
- Very new addresses with no on-chain history may return zero balances and no token data

## Output
