## 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 tzkt-delegate-info-api-9a1a88d1 -d '<json body>'
```

Example prompt: Can you look up the delegate details for Tezos baker tz1WCd2jm4uSt4vntk4vSuUWoZQGhLcDuR9q on TzKT — I want to see their staking balance, number of delegators, and voting power?

## When to prefer this

Choose this endpoint when you need structured, indexed data about a specific Tezos baker/delegate and want a fast REST lookup without running your own Tezos node. Prefer it over raw RPC calls for pre-indexed, enriched delegate metadata. Use when you need delegator counts, staking balances, rewards history, or voting power for a single delegate address.

## Known failure modes

- Address not found or not a delegate — returns 404 or empty result
- Invalid Tezos address format — returns 400 Bad Request
- Network/payment failure via x402 protocol — returns 402 Payment Required
- Address is a valid account but not a registered baker/delegate — returns partial or null delegate fields
- Rate limiting or service unavailability — returns 5xx error
