## 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 saylor-innovations-data-desk-tezos-account-lookup-b8e279c6
```

Example prompt: What's the current XTZ balance, staked amount, and baker delegation for the Tezos address tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb?

## When to prefer this

Choose this endpoint when you need a comprehensive on-chain snapshot of any Tezos account — implicit (tz1/tz2/tz3) or smart contract (KT1) — including balance, staking, delegation, and activity history in a single call. It is ideal for agents doing Tezos wallet verification, airdrop qualification checks, baker delegation audits, or DeFi analytics on the Tezos blockchain. Prefer it over raw TzKT API calls when you want a pre-processed, agent-ready JSON response with a simple address parameter.

## Known failure modes

- Invalid or malformed Tezos address returns an error or empty result
- Address not found on-chain (never used) may return zeroed fields or a 404
- TzKT upstream unavailability causes failure or stale data
- KT1 contract addresses may have limited fields compared to implicit accounts
- Payment failure (x402) if USDC balance is insufficient
