## 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`):

Example prompt: Can you pull up all the smart contracts originated by the Tezos address tz1abc123... on TzKT, showing the first 20 sorted by time descending?

## When to prefer this

Use this endpoint when you need to enumerate smart contracts originated by or attributed to a specific Tezos account address. Prefer this over general contract search endpoints when you already have a known account address and want to see all its associated contracts. Ideal for wallet explorers, DeFi dashboards, auditing smart contract deployments, or building developer tooling on Tezos.

## Known failure modes

- Invalid Tezos address format returns 400 or empty array
- Address not found on-chain returns empty array
- Invalid sort field or direction returns 400 error
- Limit or offset out of bounds returns 400 error
- Network or upstream indexer unavailability returns 5xx error
- Payment failure (insufficient USDC balance) blocks the request via x402
